WASHINGTON, Aug. 21 (Xinhua) -- U.S. officials on Wednesday acknowledged reports that a U.S. military drone was shot down in Yemen late Tuesday.
"We are investigating reports of an attack by Iranian-backed Houthis forces on a U.S. unmanned aerial system operating in authorized airspace over Yemen," a spokesman with the U.S. Central Command said in a statement.
The drone is reportedly an MQ-9 model, which was believed to be hit by a surface-to-air missile.
Yemen's Houthi rebels said they shot down an MQ-9 drone over the Yemeni central province of Dhamar on Tuesday night, Houthi-run al-Masirah TV reported.
"The U.S. drone was shot down by a locally-made missile," the television quoted a statement by the group's military spokesman Yahya Sarea as saying.
In June, the U.S. Central Command confirmed that an MQ-9 drone was shot down over Yemen, suggesting that Iran was involved in it. Iran had denied the allegation.
