At least 6 Kurdish fighters are killed in a drone attack on a Syrian base housing US troops

BEIRUT -- A drone attack on a base housing U.S. troops in eastern Syria killed six allied Kurdish fighters late Sunday, in the first significant attack in Syria or Iraq since the U.S. launched retaliatory strikes over the weekend against Iran-backed militias that have been targeting its forces in the region.

The U.S.-backed, Kurdish-led Syrian Democratic Forces said Monday the attack hit a training ground at al-Omar base in Syria’s eastern province of Deir el-Zour and accused “Syrian regime-backed mercenaries” of carrying out the attack. No casualties were reported among U.S. troops.

An umbrella group of Iran-backed Iraqi militias, dubbed the Islamic Resistance in Iraq, released a video claiming responsibility for the attack and showing them launching a drone from an unspecified location.

In late January, a drone attack by the same group killed three U.S. troops and wounded dozens more at a desert base in Jordan. The U.S. military launched dozens of retaliatory strikes targeting Iran-backed militant groups in western Iraq and eastern Syria and also struck the Houthis in Yemen.

The umbrella group has launched dozens of drone attacks on U.S. military bases and troops in Iraq and Syria, and has called for the withdrawal of American soldiers from both countries.
