German Foreign Minister Guido Westerwelle has urged that the International Criminal Court(ICC) should be tasked to examine an alleged chemical weapons use in Syria."I have again pressed for the UN Security Council to give a mandate to the ICC to examine the chemical attack in Syria," Westerwelle made the remarks on Thursday on the sidelines of the G20 summit in Russia's Saint Petersburg. "We have launched this initiative already in January," he said, adding, "The situation has worsened sufficiently for another initiative." The German foreign minister also condemned any use of banned arms and said, "Naturally, use of chemical weapons is absolutely unacceptable." This comes as the US insists on waging military action against the Arab country despite a growing global opposition to such a move. The US war rhetoric against the country intensified after Syria militants claimed the army had carried out a deadly chemical weapons attack in the suburbs of the Syrian capital Damascus on August 21, which killed hundreds of Syrians. Damascus has vehemently denied the accusations, saying the chemical attack was carried out by the militants themselves as a false-flag operation. On August 31, US President Barack Obama said he had decided that Washington must take military action against the Syrian government, which would mean a unilateral military strike without a UN mandate. Obama said despite having made up his mind, he will take the case to the US Congress. But he added that he is prepared to order military action against the Syrian government at any time. Syria has been gripped by deadly unrest since March 2011. According to the United Nations, more than 100,000 people have been killed and millions of others displaced in the violence in the country.
