(CNN) -- Three people died Tuesday in an explosion in the Turkish capital Ankara, in what may have been a terror attack, Interior Minister Idris Naim Sahin told CNN sister network CNN Turk. "There was a powerful explosion in a car that was parked," the minister said, citing preliminary information. "The possibility that it was a terrorist attack is high." He said it was also possible that a gas explosion had caused the blast, "though that is a weak possibility." The explosion shook a crowded street in the center of Ankara, damaging vehicles and buildings on Kumrular Street near the Kizilay metro station, the official Anatolia news agency reported. An eyewitness described the scene as "terrible" and "very chaotic." "Cars were exploding. Pieces were spreading around. We were terrified," the unnamed witness told CNN Turk. Deputy Prime Minister Besir Atalay said earlier there were no deaths, but 15 people were wounded, Anatolia reported. Ankara governor Alaaddin Yuksel said officials, including police and a prosecutor, were investigating the cause of the blast. He said many cars were parked on the street with garbage bags under them at the time of the explosion. Five people are in surgery, he added. An emergency services doctor at Numune Hospital in Ankara said 10 injured people were brought to the hospital. One was in intensive care, one was in the burn unit and the other eight have light injuries, said the doctor. None of the injuries are life-threatening, said the doctor, who did not give a name. Doctors in state hospitals are not allowed to speak to the media. The explosion took place in front of the Cankaya municipal building, local official Bulent Tanik said on Turkish television. He cited eyewitnesses as saying a burning gas tank had been thrown out a window onto the street. Police have sealed off the street, Anatolia reported. --CNN's Yesim Comert and Talia Kayali contributed to this report.

(CNN) -- Violence between competing unions at South Africa's mines is threatening to weaken Africa's largest economy. On Wednesday, the world's top platinum producer, Anglo American, suspended all of its operations in Rustenburg, South Africa due to "intimidation" of its workers. Striking workers are also halting operations at some gold mines. The move follows strike-related violence at Lonmin's Marikana mine in August that left 44 dead. What triggered the violence? The 34 miners in the Lonmin mine in Marikana, South Africa, died after police opened fire on a gathering of thousands of machete-armed workers striking for higher wages. The shootings came after deaths earlier in the week, including those of two police officers who were hacked to death. The violence exploded when police shot at striking rock drillers in the "Easterns" area of the Marikana mine. Tensions have been high in part because of the presence of competing trade unions, the Association of Mineworkers and Construction Union (AMCU) and the National Union of Mineworkers (NUM). Read more: Inquiry launched into mine shootings . The mine, about two hours northwest of Johannesburg, is operated by Lonmin, which is listed on both the London Stock Exchange and Johannesburg Stock Exchange, and is the world's third largest platinum producer. The bulk of its 28,000 employees work at the mine, and around 23% belong to the AMCU. The violence has prompted some people to draw parallels with the country's days of apartheid rule, which ended in 1994. South African's president, Jacob Zuma, has opened an inquiry into the incident. What is behind the conflict? Rivalry between the AMCU and the NUM is widely blamed for feeding the violence. The AMCU, which has expanded rapidly this year at the expense of NUM, is seen as the more militant union and has been linked to aggressive tactics to win wage increases. It has gained ground in an environment where workers have been dissatisfied with improvements in quality of life since the end of apartheid, particularly for those in the lower wage brackets. At Marikana, 3,000 rock drill operators at the mine stopped work as they tried to force an increase in their wages, from ZAR5,400 ($648) a month to ZAR12,500 ($1,500) a month. Tensions increased over the following days, with AMCU president Joseph Mathunjwa declaring the members were prepared to "die here" if necessary. The stand-off later escalated into violence, leaving 34 dead, 78 injured and 259 arrested on various charges, according to South Africa National Police Commissioner Riah Phiyega. The violence follows other fatal incidents including a six-week strike at Impala Platinum (Implats) in February, which left three dead, and an attack on Aquarius Platinum in August which also left three people dead. The push for higher wages comes after the AMCU was "clearly emboldened" by a strike at Implats' Rustenberg mine in February which resulted in a 125% increase in wages, analysts at Eurasia Group noted. The outcome set a "problematic precedent for platinum companies in South Africa," Africa analyst Mark Rosenberg said. Alison Turner, analyst at Panmure Gordon & Co, said the emergence of the AMCU "represents the single biggest risk to the platinum sector, particularly as many of the incidents in which the AMCU has been implicated have involved violence." According to Rosenberg, however, violence at Marikana could prove to be detrimental to the union's aggressive recruitment strategy. Who is to blame for the Marikana shootings? While union rivalry is being blamed for the friction, it is unclear who triggered the first shots at Marikana, which is one of the country's bloodiest incidents since the end of apartheid in 1994. Police have said they were bringing in barbed wire to fence the miners, and used tear gas and stun grenades to disperse them. According to Phiyega, a militant group of strikers then fired on police who said they were forced to use "maximum force" to defend themselves. Video from the incident shows police shooting for some minutes at protesters, kicking up dust. When the dust clears, several bodies are shown lying on the ground. The video appeared to show the police response was "very forceful," Turner said. The South African Institute for Race Relations said that policemen randomly shot into the crowd with rifles and handguns. "There is also evidence of their continuing to shoot after a number of bodies can be seen dropping and others turning to run. This is reminiscent of the Sharpeville massacre in 1960," the institute said. In a press conference Phiyega said it was not a time for placing blame, but "a time for us to mourn." Late last month, a regional prosecutor charged 270 of the platinum miners with the murder of their colleagues, who are believed to have been shot by police. However, the charges are being dropped. What do the unions say? The two implicated unions, accused of trying to outdo each other in negotiating wages, denied instigating the clashes. AMCU general secretary Jeff Mphahlele told CNN the union could not be blamed. "We are a peaceful organization and we do not condone violence," he said. Mphahlele said police initially shot at the protesters from behind, although when asked if they shot first he said: "I was not there," adding: "The killing of those people was not necessary." He said Mathunjwa's reference to being prepared to die was in response to fears the police would attack. Frans Baleni, head of the NUM, said Monday that its members were under siege. "Our members have been attacked, and that cannot be said to be clashes or rivalry, it is pure criminality," he said. Is the government tarnished? The NUM is a close ally of the country's ruling African National Congress and its inability to stop the violence and weakened role is expected to drag on Zuma, according to Rosenberg. The immediate impact is likely to be Zuma's pitch for re-election to head the party in December, he added. Re-election is "significantly less likely" Rosenberg said. While there is no formal challenger to the role yet, this could spur the emergence of one, he added. People are no longer willing to sit and wait around for the ANC to deliver, Rosenberg said. "They are becoming more and more impatient and they're becoming more and more violent as a result." What is the impact on Lonmin? Lonmin has so far missed out on around $75 million in lost production, and the workers haven't been paid for a month. The company said last week that a "peace accord" had been signed, but key unions had not agreed to the deal. Lonmin acting CEO Simon Scott said the company and unions have agreed to "negotiate to address the wage demands within a legal framework." He added, "We simply ask that those negotiations happen in an environment free of intimidation and violence." The company has previously announced its chief executive Ian Farmer had been diagnosed with a serious illness and was in hospital. It was unrelated to the mine incident.

(CNN) -- For the first time since a reported massacre there, U.N. observers on Saturday entered the Syrian town of Tremseh, where opposition activists say more than 200 people were killed. The violence took place Thursday, on what may have been the single deadliest day in the 16-month crisis. It prompted a fresh round of condemnation from world leaders. In Tremseh, the U.N. team found evidence of an attack, including a burned school, damaged houses, and proof that artillery, mortars and small arms were used, said Sausan Ghosheh, spokeswoman for the head of the U.N. Supervising Mission in Syria. She added that the number of causalities remains unclear. "The attack ... appeared targeted at specific groups and houses, mainly of army defectors and activists. There were pools of blood and blood spatters in rooms of several homes together with bullet cases," Ghosheh said in a statement. U.N. observers are expected to return to the town Sunday to continue their fact-finding work. Still grappling with the attack, Syrians endured yet another bloody day Saturday as regime forces fired from low-flying helicopters and a bomb exploded at a state security headquarters, opposition activists said. At least 73 people were killed in Saturday violence, including 20 in Homs, 11 in Damascus Suburbs and 13 in Hama province, the Local Coordination Committees of Syria said. Fourteen additional deaths were reported in Deir Ezzor and 12 in Idlib, among others. Another opposition group, the Syrian Observatory for Human Rights, said a car bombing targeted a state security building in Hama, and "a number of state security personnel were killed and wounded." Syrian state-run TV said at least three civilians and a security officer were killed in Muhrada by a suicide bomber in a truck. Farther south, the Daraa province town of Khirbet Ghazaleh came under heavy shelling and machine gun fire after the Syrian army surrounded it with tanks, the LCC said. "Helicopters fly over the city at a low altitude with a continued siege of the city and gunfire from snipers," the opposition network said. Meanwhile, Deir Ezzor was subject to intense shelling by government forces, as well as fierce clashes between regime forces and the Free Syrian Army, the LCC said. How long can al-Assad hang on? According to the opposition network, more than 200 villagers were killed in the Hama-area town of Tremseh on Thursday, and dozens more were killed elsewhere across the country. U.N. spokeswoman Ghosheh said a large patrol had been sent from Damascus to Tremseh on Saturday to assess the situation, amid widely differing accounts of what happened from opposition activists and the government. An initial reconnaissance mission was sent Friday following assurances of a cease-fire in the area, the spokeswoman said, but it was too late in the day to do much. "The patrol assessed the situation -- if there was in fact a cease-fire and our access to the town," she said. "An 11 vehicle integrated patrol, comprised of specialized military and civilian observers, arrived ... on Saturday after confirming that a cease-fire was in place." International anger against Syrian President Bashar al-Assad has ratcheted up since the Tremseh incident, with at least one U.S. official suggesting the need for more pressure on al-Assad's regime. As outrage grows in Syria, report of a 'breakthrough' for humanitarian aid . "Through these repeated acts of violence against the Syrian people, President Assad has lost legitimacy to lead. It is time for him to go. It is time for the political transition that is long overdue to finally get under way," Josh Earnest, a White House spokesman, told reporters Friday. "It certainly does build strong international support ... to continue to ramp up the pressure on Assad," he added, citing "ongoing conversations at the United Nations about additional ways that we can build some international agreement and raise the stakes even further." Syria moving chemical weapons? Activists in the city of Hama, meanwhile, gave a grisly account of the assault in Tremseh. Witnesses inside the town told the activists by telephone that Syrian military forces had launched a full-scale attack against the opposition Free Syrian Army inside the town, which was surrounded by government tanks and artillery. As the government forces rained artillery rounds into the town, a number of village residents fled their houses, going into the streets, where many of them were shot dead by the government militias, the activists told CNN. The government painted a starkly different picture of Tremseh than that detailed by opposition groups. The state-run Syrian Arab News Agency blamed "armed terrorist groups" for the violence. It said the government said residents called security forces for help after the terrorist groups raided the neighborhood. Regime forces arrested some of the members of the terrorist groups and confiscated their weapons, the government said. Syria's detached and deluded elite? "Armed forces successfully dealt with the terrorists without casualties taking place among the citizens. They searched into the terrorists' dens where they found the dead bodies of a number of citizens who had been abducted and killed by the terrorist groups," SANA reported, citing a military source. CNN cannot independently verify reports from Syria because the nation has restricted access by international journalists. Meanwhile, many who survive the violence are caught in a precarious humanitarian situation. The chief U.N. organization that coordinates emergency aid warned Friday that more Syrians will die if contributing nations do not follow through and fund its relief operation. "We have run out of language to describe how it is for the civilian population," said John Ging, operations director and chairman of the Syria Humanitarian Forum for the U.N. Office for the Coordination of Humanitarian Affairs. "It is physical and it is psychological." CNN's Saad Abedine, Dan Lothian and Hamdi Alkhshali contributed to this report.
