JERUSALEM (AP) — Yemen’s Houthi rebels on Saturday claimed shooting down another of the U.S. military’s MQ-9 Reaper drones, airing footage of parts that corresponded to known pieces of the unmanned aircraft.

The Houthis said they shot down the Reaper with a surface-to-air missile, part of a renewed series of assaults this week by the rebels after a relative lull in their pressure campaign over the Israel-Hamas war in the Gaza Strip.

U.S. Air Force Lt. Col. Bryon J. McGarry, a Defense Department spokesperson, acknowledged to The Associated Press on Saturday that “a U.S. Air Force MQ-9 drone crashed in Yemen.” He said an investigation was underway, without elaborating.

The Houthis described the downing as happening Thursday over their stronghold in the country’s Saada province.

Footage released by the Houthis included what they described as the missile launch targeting the drone, with a man off-camera reciting the Houthi’s slogan after it was hit: “God is the greatest; death to America; death to Israel; curse the Jews; victory to Islam.”
