US Secretary of State John Kerry said on Thursday that the US may increase its support to the opposition armed groups operating in Syria, although he did not say whether this would include sending them weapons.

During a meeting with Western and Gulf allies on Syria held in London, Kerry indicated there has not been a decision on changing US aid strategy to Syria, claiming that he has seen raw data that suggests the Syrian army may have used chlorine gas on its own people.

The French Foreign Minister Laurent Fabius also said that chlorine may have been used 14 times in recent months. Although Kerry stressed that the data has not been verified.
