[EX Q]: (CNN) -- Thousands on Saturday fled the area in southwestern Ivory Coast where attacks left seven U.N. peacekeepers and eight civilians dead, according to a U.N. official. One attack occurred late Thursday and into Friday near Para Village, not far from the west-central African nation's border with Liberia, according to the United Nations. Humanitarian organizations reported Saturday they were expecting about 4,000 people in Tai, said Remi Dourlot, a spokesman for the U.N. Office for the Coordination of Humanitarian Affairs. Several hundred had arrived by midday Saturday in the town, which is on the edge of Tai National Park. Another 35 families crossed the Ivory Coast's southwest border into U.N. refugee camps in Liberia, and humanitarian groups said hundreds of others had been pushed south by the violence, according to Dourlot. The movement comes after blue-helmeted peacekeepers -- who were in the area because of threats against civilians -- came under attack, the United Nations said in a statement. Besides the U.N. peacekeepers, humanitarian groups reported eight civilians died in violence, said Dourlot. U.N. Secretary-General Ban Ki-moon on Friday called on the government of Ivory Coast "to do its utmost to identify the perpetrators and hold them accountable." He added that he understood other peacekeepers remained in danger. "Even tonight, after the attack, more than 40 peacekeepers remain with the villagers in this remote region to protect them from this armed group," Ban said. U.N. Operation in Cote d'Ivoire and Ivory Coast troops have increased their presence in the area, Dourlot said Saturday. Members of the U.N. humanitarian affairs office have deployed to Tai to coordinate relief efforts there with local authorities. Clinton urges Ivory Coast dialogue . A spokeswoman for the U.N. mission in Ivory Coast said Friday's incident was the first attack on peacekeepers since they entered the country in 2004. Sylvie van den Wildenberg, in a telephone interview from her office in Abidjan, said the remaining forces were continuing to protect area residents, "who are living in a very difficult terrain -- their villages scattered." Van den Wildenberg said it was not clear who was responsible for the attack, which occurred mid-afternoon. "This is an area where you have so many different types of armed people," she said. "People have different aims and different reasons to carry arms and to perpetrate attack. So this is a very complex environment. We can't extrapolate. We just can't fingerpoint any group." The peacekeepers were on a reconnaissance patrol because U.N. officials had heard rumors several days earlier of armed men in the area threatening to attack a village, she said. U.N. peacekeepers remained in Ivory Coast after the 2010 presidential election, when the country was thrown into crisis after incumbent President Laurent Gbagbo refused to acknowledge defeat to former Prime Minister Alassane Ouattara. The latter was sworn in on May 21. Gbagbo is in custody at the Hague, accused of crimes against humanity during post-election violence that killed thousands. According to the United Nations, its peacekeeping force in Ivory Coast as of April 30 included nearly 11,000 uniformed personnel, as well as several hundred international civilian personnel, local staff and volunteers. They provide technical, logistical and security support to the government. CNN's Christabelle Fombu and Tom Watkins contributed to this report.

[EX Q]: (CNN) -- Lewis Hamilton realistically can't win the title but the former world champion hopes to challenge powerhouse Sebastian Vettel at the Korean Grand Prix after posting the fastest practice times Friday. Hamilton's time of one minute, 38.673 seconds in the second session in Yeongam was about one-tenth of a second quicker than Vettel, the triple reigning world champion who has captured the last two races in Korea. "It's the first time I can remember that second practice has really gone well for me," Mercedes' Hamilton was quoted as saying by Formula One's website. "We haven't changed anything but the day just went smoothly and all the processes with the team worked well. I love this track." Vettel admitted there was "some room for improvement" in his Red Bull. "It will be close with Mercedes," he told Formula One's website. "Of course we're not sure what others were doing with their fuel loads today, but it seems close ahead of tomorrow's qualifying. "I like the track here, it's a shame it's so far from Seoul, which is a great city, but it's good coming here as it's quieter than some other races, which means we can focus on our job." The only driver with half-a-chance of catching Vettel, Fernando Alonso, was a distant seventh in the second session. He trails Vettel by 60 points with a mere six races remaining and admitted this week he needed a comeback similar to Oracle Team USA's in the America's Cup sailing to overtake the German. But Alonso didn't sound optimistic Friday. "There is every probability that, again here, we can expect to struggle in the race," Ferrari's Alonso told Formula One's website. "It won't be easy for us in performance terms, but we know that apart from that, we can do well on Sunday. Now, we must try and get the most out of what we have available and put everything together tomorrow and in the race." Kimi Raikkonen, Alonso's teammate next season, crashed in the first practice session but was unhurt. Autosport.com quoted the Finn as saying he would take action at the end of the season to fix a lingering back problem. "It is not really surgery, but for sure we are probably going to do something," said Raikkonen. "I know what the issues are."

[EX Q]: (CNN) -- Efforts to rescue a research crew aboard a ship stuck in ice off Antarctica stalled Thursday after sea ice conditions made a key element of the rescue plan risky, Australian maritime officials said. The rescue plan called for a helicopter to ferry the passengers from the MV Akademik Shokalskiy to a Chinese vessel, where they would then board a barge to take them to an Australian icebreaker, the Australian Maritime Safety Authority (AMSA) said in a written statement. But the shifting ice conditions prevented the barge from being able to reach the Chinese vessel, the statement said. "Alternative measures to complete the rescue operation are now being investigated by AMSA and the ships involved," the statement said. The news is the latest chapter in a saga that began Christmas Eve after the Russian-flagged MV Akademik Shokalskiy got stuck in 10 feet of ice. Even if the rescue begins Friday, it will still be weeks before the research team will make it to Hobart, Australia, John Young of the Australian Maritime Safety Authority said. "Mid-January is our best guess," Young told reporters on a conference call. The rescue plan called for the helicopter, which can transport 12 people each trip, to ferry the ship's 52 passengers -- who include the research team and journalists -- to the Chinese icebreaker called the Snow Dragon, or Xue Long, the maritime agency said. The 22 Russian crew members of the Akademik Shokalskiy will stay aboard, it said. The passengers are then to be transported by barge from the Chinese ship to the Australian icebreaker Aurora Australis. That's because the Chinese helicopter can't land on the Australian icebreaker because of load restrictions, and ice conditions make it unsafe to land it next to the ship, AMSA said. "The preferred option is to wait for conditions that will allow the rescue to be completed in a single operation to reduce unnecessary risk," the maritime agency said. The master of the Akademik Shokalskiy has decided to keep the crew members on board until the pack ice eventually breaks up and allows the ship to move again, Young said. The vessel has enough supplies to keep the crew going for "a very long time," he said. Failed rescues . The planned helicopter rescue follows a failed attempt by the Chinese icebreaker, which made it six nautical miles from the trapped vessel before being stopped by the ice. That was followed by an effort by the Australian icebreaker, which was forced Monday to suspend efforts to reach the expedition because of bad weather. The Aurora Australis got within 10 nautical miles of the ship before it turned back. Over the weekend, an effort by the French icebreaker Astrolabe was called off by the maritime agency. In preparation for the helicopter rescue, members of the research team as well as the crew of the Akademik Shokalskiy marked a makeshift helipad on the ice where the helicopter can land. Video clips posted online by the research team showed people, with arms locked, walking to tamp down the snow. "As we understand, the helipad was suitable yesterday and will be suitable today," AMSA's Richard Wallace said. Once the passengers are safely aboard the Aurora Australis, the ship will complete a resupply mission to Casey Station, an Australian base in Antarctica, before making its way to Hobart, the maritime agency said. Viral sensations . The exploits of the research crew have gone viral, thanks in large part to Twitter and YouTube posts by those aboard the stranded vessel. Chris Turney, an Australian professor of climate change at the University of New South Wales, has tweeted photos of the stranded ship, the crew and penguins, who he said -- according to one post on Twitter -- "to check out what's going on." "The group on this ship is incredibly collegiate," said Alok Jha, a science correspondent for The Guardian newspaper, told CNN's Anderson Cooper 360. "There are a lot of skills and things people are sharing with each other." Turney has said there are regular briefings on the status of rescue attempts, and in the meantime, people are doing what they can to keep busy. That includes yoga and Spanish classes, Jha and Turney said. The group even managed to ring in 2014 with good cheer. "We're the A, A, E who have traveled far, having fun doing science in Antarctica!" a dozen or so of them sang in a video posted on YouTube. "Lots of snow and lots of ice, lots of penguins, which are very, very nice! "Really good food and company, but a bloody great shame we are still stuck here! Ice cold, cha cha cha! Ice cold, cha cha cha!" Spirits strong among passengers on ship stuck in Antarctic ice . CNN's Radina Gigova and Jethro Mullen contributed to this report.
