Drone Attack Targeted US Forces in Iraq: US Official

U.S. forces stationed at Iraq's Ain al-Asad airbase were targeted in an armed drone attack that caused no damage or casualties, a U.S. official said, in the second attack on U.S troops in the region in less than 24 hours.

The attacks follow a near-three month pause in the targeting of U.S. forces in Iraq and Syria after months of near-daily rocket and drone strikes by Iran-backed Shi'ite Muslim armed factions over U.S. backing of Israel's Gaza campaign.
