US troops in northeastern Syria were attacked by a drone, a US official has told Reuters on Friday, although there were no injuries according to initial reports.

This is the second attack in recent days against US forces in the Middle East as the region braces for a possible new wave of attacks by Iran and its allies.

“Initial reports do not indicate any injuries, however, medical evaluations are ongoing. We are currently conducting a damage assessment,” the US official said on the condition of anonymity about the attack in Syria.

The attack took place at Rumalyn Landing Zone, which hosts US troops along with those from the US-led coalition.

The United States has 900 troops in Syria and 2,500 in neighbouring Iraq.
