U.S. troops based in Syria have been attacked several times within hours, an Iranian-backed group has said, as fears grow that hotspots of violence in the Middle East, including the Israeli-Palestinian conflict, could flare into broader bloodshed.

The Iranian-backed Islamic Resistance in Iraq group targeted the Al-Tanf military base, hosting U.S. troops in southern Syria, with two drones on Wednesday, representatives for the movement said in a statement.

The drones struck their intended targets, the group claimed. The Al-Tanf base has housed U.S. troops since 2016, close to the Syrian border with Iraq and Jordan.

The previous day, Islamic Resistance in Iraq said it had attacked the Ain al-Asad airbase, 135 miles northwest of Baghdad, where U.S. troops are stationed, with the two drones striking the facility.
