The U.S. military said on Thursday a blast on Sunday near a UNESCO world heritage site in Yemen's capital city of Sanaa was caused by a Houthi missile and not an American airstrike.

The attack, which killed at least 12 people, was the deadliest on Ukraine’s capital in nearly a year. President Trump called on President Vladimir V. Putin to “STOP!” in a post on social media.

Russian attack drones and ballistic missiles struck the capital, according to the Kyiv City Military Administration.
