The U.S.-led coalition against Islamic State has boosted support for its Syrian allies since President Donald Trump took office, supplying armored vehicles for the first time as they prepare to launch a new phase in their campaign for Raqqa, a spokesman for the militia said on Tuesday.

The U.S.-backed Syrian Democratic Forces (SDF) alliance, which is dominated by the Kurdish YPG militia, is waging a campaign aimed at taking Raqqa city, Islamic State¡¯s base of operations in Syria.

A Pentagon spokesman said on Tuesday the vehicles had been supplied to Arab elements within the SDF ¡°as part of our existing authorities to enable them,¡± and there had been no change in policy.
