The Saudi-led coalition warplane bombed a crowded funeral hall in Yemen's capital Sanaa. An investigation has concluded that the coalition believed it was a gathering of rebel leaders.
Despite the U.S. strike, the Obama administration still hopes to keep America's role in Yemen's war offshore, with Saudi Arabia and other Arab militaries doing the actual fighting.
The U.S. launched missiles at three radar installations in Yemen late Wednesday. It's the first time that the U.S. has carried out strikes against the Houthi rebels during the conflict in Yemen.
The Pentagon says twice in four days a missile was fired from Yemen at the USS Mason, with no damage to the ship or its crew. An official says the U.S. has destroyed radar locations in response.
The U.S. has been supporting Saudi Arabia's bombing campaign in Yemen for more than a year. An airstrike that killed at least 140 people at a funeral has renewed a debate about U.S. involvement.
The bombing struck the southern city of Aden, the temporary home of Yemen's government. An ISIS-affiliated news outlet says the attack targeted a military recruitment center.
The group deemed six facilities "unsafe" after a hospital was hit by a Saudi-led- coalition airstrike and said it has lost confidence in the coalition's "ability to prevent such fatal attacks."
