Britain has sent a letter to Secretary-General Ban Ki-moon with new information of alleged chemical weapons use by the Syrian government. According to AP, Britain's U.N. Ambassador Mark Lyall Grant said Thursday that his government has continued to update the secretary-general and the head of the U.N. team Ban appointed to investigate the alleged chemical weapons attacks with new information. "I sent a further notification to the secretary-general last week," he told several reporters. Lyall Grant said Britain believes all the alleged chemical weapons attacks are by the government. He said the British government has no evidence that the opposition has obtained chemical weapons or used them.
