GENEVA, March 14 (Reuters) - Syria’s air force deliberately bombed water sources in December, a war crime that cut off water for 5.5 million people in and around the capital Damascus, the U.N. Independent International Commission of Inquiry on Syria said on Tuesday.

The commission said it had found no evidence of deliberate contamination of the water supply or demolition by armed groups, as the Syrian government maintained at the time. (Reporting by Tom Miles; Editing by Dominic Evans)
