Journalist Marie Colvin’s sister Cat said she and her lawyer have evidence that the Syrian government specifically attacked Colvin when she was killed by a rocket while covering the siege of Homs in Syria.

Court documents released said a former Syrian intelligence agent alleges an informant told the Damascus government about Colvin's location the night before she was killed.

Her lawyers said the attack was deliberate on the media centre and while they acknowledge getting money from the Assad regime is unlikely, they hope the case can help establish evidence of ‘a chain of command’ to be used in possible future war crime trials.
