Yemen’s Houthi rebels alleged an American airstrike killed at least 68 people and injured scores more in a detention center holding African migrants in northern Yemen on Monday, one of the deadliest attacks in the six-week-long U.

Corpses covered in dust and debris were scattered in the wreckage of a detention centre for African migrants in Yemen, after what Houthi-controlled television described on Monday as a U.S. airstrike that killed 68 people.

Yemen's Houthi rebels say a U.S. strike has hit a detention center for migrants in Saada, killing dozens of people.
