PROBLEM: (CNN) -- Libyan Deputy Foreign Minister Abdelati Obeidi flew to Greece Sunday to deliver a personal message from Libyan leader Moammar Gadhafi, a Greek foreign ministry official told CNN. Libya asked Greece to allow a special envoy to travel there to communicate a message, Greek foreign ministry spokesman Grigoris Delavekouras said. The nature of that message was not immediately known. Obeidi met with Greek Prime Minister George Papandreou Sunday night, according to Greek Foreign Minister Dimitris Droutsas. "We stressed -- reiterated -- the clear message of the international community. One of full support and implementation for the decisions of the United Nations, immediate ceasefire and an end to violence, particularly against Libyan civilians," Droutsas said after the meeting. "From what the Libyan envoy said, it is clear that the administration is looking for a solution," he added. Obeidi is expected to continue talks in Turkey and Malta, according to Droutsas. The envoy crossed the Libyan border into Tunisia Sunday morning, and from there boarded a private Greek plane for Athens. Obeidi is the Libyan deputy foreign minister in charge of European affairs. Journalists Houda Zaghdoudi and Elinda Labropoulou contributed to this report .

PROBLEM: (CNN) -- Earlier this month, an AeroMexico plane made an important flight from Mexico City to Madrid. The flight wasn't notable for who was inside the cabin, but for what was inside the fuel tank: it was the world's first transatlantic commercial flight using biofuel. The engines on that flight were powered by a fuel mixture that was 30% biofuel from the jatropha plant, and the trip followed a pair of Mexican domestic commercial flights by Interjet that used the same formula. Mexico is known for its oil production, but it could be its less obvious flats of arid and marginal land that will be the future of Mexico's energy resources. The country has quietly positioned itself to become a potential leader in biofuel production as scientists develop a second generation of fuels derived from sources that don't compete for arable land or with food. Jatropha-based biofuels are being increasingly used in Mexico, and agave -- the plant from which tequila is made -- is being studied as a new source for ethanol. But some observers warn that Mexico's cumbersome land laws make it too hard to purchase the land needed for cultivation at competitive prices. Some biofuels, such as ethanol derived from corn and sugar, can indirectly raise the prices of staple foods in many places, along with raising ethical issues, said Gilberto Lopez Meyer, director of Airports and Auxiliary Services (ASA), the Mexican government agency that oversaw the biofuel flights. So in 2007, Mexico, along with 14 other member countries of the International Civil Aviation Organization, committed to developing new strategies for second-generation biofuels that would not affect food production. "We returned to Mexico with a mission," Lopez told CNN. Lopez's agency teamed up with the state of Chiapas, where Gov. Juan Sabines had already made a name for himself pushing his state toward alternative fuels. Chiapas began cultivating jatropha, whose seeds contain oil that can be extracted and converted into biofuel. The state already uses a jatropha biofuel mix on its buses and trucks, and President Felipe Calderon was on hand in November of last year to inaugurate a biodiesal plant there. ASA partnered with American company UOP, which refined the Chiapas jatropha into jet fuel. When the standards for biofuel use in commercial flights was approved July 1, Mexico was ready to make the domestic Interjet and international AeroMexico flights a possibility. The goal of ASA, which provides almost 100% of the jet fuel in Mexico, is to commercialize and distribute biofuels, Lopez said. "We've been working on this project as part of a global effort to combat climate change," he said. By 2015, the goal is to have 1% of all jet fuel in Mexico be biofuel, and by 2020, 15%, he said. "This is a huge goal," Lopez said. "One percent doesn't sound like a lot, but it equals more than 40 million liters (10.6 million gallons)." Mexico has several things in its favor to become a leader in biofuels, he said. It has plenty of land not being used for food, it has a high demand for energy, and it is located next door to the energy-hungry United States. "Mexico has made the very important first step to be in a very priviledged place," Lopez said. Halfway across the world, researchers at Oxford recently published a study extolling the benefits that ethanol derived from agave. Agave can grow in arid land, and produces less than half of the carbon dioxide emissions produced by corn-based ethanol, Oliver Inderwildi, one of the study's authors, told CNN. Sugar-based ethanol produces even less emissions, but it needs arable land for cultivation. "We need every space we can get, every arable land, for food," Inderwildi said. "We think agave may be one part of the solution." For their study, the researchers did a life-cycle analysis for the production of ethanol based on a hypothetical plant in Jalisco, Mexico, where 90% of tequila is produced. Potentially, agave plantations could boost local economies and create jobs, Inderwildi said. Mexico, the native home of agave plants, stands to benefit if such an ethanol industry takes off. Food prices would be spared, but would drinkers have to pay more for their margaritas and tequila shots? The tequila business is very small compared to the fuel business, and is also more expensive than fuel ethanol, so Inderwildi predicts that alcohol prices would remain stable. And unlike tequila, which requires the harvesting of the agave stem only, ethanol production would also require harvesting the leaves of the plant. "Our study backs up that this is a good idea from an environmental perspective," he said. The catch, for now, is that neither jatropha or agave biofuel production is cost-effective. But technological advances and oil prices make such alternatives more desirable. When that tipping point comes, Mexico will be ready, the experts said. But James Row, CEO of Houston-based Producers Energy and part owner of a Mexican-based biodiesel company, told CNN that Mexico is still far from being an ideal place to produce biofuels. "Mexico is absolutely a perfect country for biodiesel, especially if it can be domestically grown," he said, but the country's ejido system -- collectively-held land in rural areas -- creates hurdles for private investment. The result is difficulty in finding continuous large areas of rural land that can be negotiated for use for cultivation, or high prices that make it cost prohibitive. Without land reform, issues with land availability will continue, and Mexico will fall a decade or more behind other countries in the biofuels sector, Row said. The demand is there, the land is there, but there is no way to get it, he said. "Now is the time for Mexico to get its act together for biofuels," he said.

It oversaw the first transatlantic commercial flight using biofuel .
The agave plant also has potential for the country .

PROBLEM: Manila (CNN)Flags were flown at half-staff in the Philippines Friday as the nation observed a day of mourning for 44 police commandos killed in a disastrous operation in the country's Muslim south. The officers, members of the police's elite Special Action Force (SAF) unit, were killed in a 12-hour firefight with two Muslim rebel groups in the southern province of Maguindanao at the weekend. Their 392-strong team had been deployed to hunt two "most wanted" terror suspects. The fallen police were farewelled by grieving family members, politicians and police and military leadership at their home base, Camp Bagong Diwa in Taguig City Friday. Policemen across the country wore black armbands to show their sympathy. Delivering a eulogy for the fallen, President Benigno Aquino III made reference to his own loss as the son of an assassinated political leader, and vowed to bring the remaining target of the commandos' mission to justice. "Our 44 fallen heroes from our police force, the youngest at 26 and the most senior at 39 years old, pushed themselves and exerted all their effort to do what they could, not only for themselves and their families, but for our beloved country," he said. "They gave up their lives for the kind of peace and order that endures." The president's father, Benigno Aquino, Jr., was a Filipino senator who was assassinated at Manila International Airport in 1983. The officers had been pursuing two "high value" terrorist bomb makers, including the senior Jemaah Islamiyah figure Zulkifli bin Hir, also known as Marwan, when they came under assault. Marwan, a Malaysian suspected of being behind the 2002 Bali bombings, has a $5 million U.S. government bounty on his head. Philippine authorities say they believe he was killed in the raid, but are yet to conduct DNA testing to confirm this. Previous reports of his death have proven false. The unit's other target, Filipino bomb maker Abdul Basit Usman, escaped. Aquino swore during the eulogy that Usman would be brought to justice. "Capturing Basit Usman is number one on our list of priorities," he said. "I assure you, we will get Usman." Police Chief Superintendent Noli G. Talino, deputy director of the Special Action Force, delivered a speech recounting how the satisfaction of the assault on Marwan soured as the commandos became pinned down during the extraction. He recalled hearing the voice of a colleague on the radio asking for reinforcements, as they became surrounded by armed rebels. "I felt guilty ... about what happened in the field, and it seems our efforts were not enough to extend the help that they have asked for. But we did our best," he said. "Is it worth it? One international terrorist equivalent to 44 SAF troopers? I'm sure if you will ask them, it is worth it." The Philippines has been fighting an insurgency in the predominantly Muslim south for years. Last year, it signed a peace agreement with the Moro Islamic Liberation Front (MILF), the largest rebel group in the region. The MILF agreed to end hostilities in return for the establishment of a more autonomous Muslim region in the south. But hardline splinter groups, such as the Bangsamoro Islamic Freedom Fighters (BIFF), have not signed any peace deal. The police commandos engaged in battle with both groups during the firefight near Mamasapano town, Maguindanao Province, last weekend. Secretary of the Department of Interior and Local Government Mar Roxas said that the commandos were retreating from the assault on their targets when they came under fire from members of the BIFF. In maneuvering away from the BIFF assault, they strayed into territory controlled by the MILF, and further fighting ensued. On Wednesday, Aquino delivered a speech to the nation vowing that the deaths would not derail the deal with the MILF, saying the fallen police had given their lives for the cause of peace. "If the peace process were derailed, how many more graves would we have to dig?" he said. "How many more children will idolize Marwan? How many will want to grow up to be Usman? How many engineers will choose to build bombs rather than buildings?" he said. A board of inquiry is looking into why the mission went wrong. The SAF has been criticized for not coordinating adequately with the MILF ahead of the mission. But Benigno said in his speech that "even if the MILF and BIFF now constitute two different groups, many of them are related by blood or by affinity. Strangers cannot just enter their territory. Our troops needed to enter quietly and carefully; otherwise, their targets may have been alerted." The MILF issued a statement Wednesday on behalf of its chairman Al Haj Murad Ebrahim. The statement reiterated the MILF's "full commitment" to the peace process, extended sympathies to the families of the fallen police and announced its own investigation into the incident. "In order to give meaning to their deaths, we must resolve not to let something like this happen again," read the statement.
