The US shifts concern about chemical weapons

""The UN has shifted concerns about chemical weapons in Syria from the regime to the rebels. They argue that pro-opposition countries could supply them to anti-Assad fighters and then blame the Syrian government. The United Nations is "genuinely worried" that some countries could supply chemical weapons to extremist groups in Syria and then claim that they were unleashed by the Syrian government, the country's UN envoy argued in correspondence made public on Monday.""
