Britain said on Sunday Russia bore responsibility by proxy for civilian deaths in Syria last week caused by a poison gas attack that Washington says was carried out by the Moscow-backed government of Syrian President Bashar Assad.

At least 70 people died in what the United States says was a chemical weapons attack in rebel-held Syria. The attack prompted the United States to fire 59 cruise missiles into a Syrian air base from which it said the attack was launched.
