YEREVAN, MARCH 9, ARMENPRESS. Several hundred US Marines have arrived in Syria to join the anti-ISIS fight in liberating Raqqa, Associated Press reports citing several sources.

Earlier Washington Post reported a group of American Marines were deployed in Syria to help the ongoing fight against Isis in liberating Raqqa.

Till now, 500 US Special Forces were operating in Syria.

The US-backed fighters are preparing to move in the coming weeks to assault the city of Raqqa, ISIS' self-declared capital, according to the officials. The Pentagon and the Marine Corps have declined to confirm the deployment because of security concerns in the region. They have also declined to specify the exact location of the forces or how many are there, CNN reported.
