Five rockets were fired at the main transit point for Syria’s chemical weapons this month, with one landing near to where experts overseeing the destruction of the toxic stockpile were staying, sources said on Tuesday.

One rocket in the March 9 strike on the Mediterranean port town Latakia landed about 500 meters (yards)from the hotel used by the joint mission of the United Nations (U.N.) and the Organisation for the Prohibition of Chemical Weapons mission (OPCW), the sources told Reuters on condition of anonymity.

The Syrian Observatory for Human Rights, a British-based monitoring group, said three rockets hit the city of Latakia, killing a taxi driver and wounding six others.
