Syria's Assad regime likely responsible for chemical attack - rights group

(Reuters) - Evidence strongly suggests Syrian government forces were responsible for a poison gas attack that killed more than 1,400 people, Human Rights Watch said on Tuesday, contradicting repeated denials by Syrian President Bashar al-Assad.

The U.S.-based rights group, in a report issued in New York, said it had reached its conclusion after analysing witness accounts, information of the likely source of the attacks, remnants of the weapons used and medical records of victims.
