At least 68 African migrants were killed and 47 injured in a U.S. airstrike on a Houthi-run detention center in northwestern Yemen, the rebel group claimed.

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

Yemen’s Houthi rebels raised the death toll Monday from an alleged U.S. airstrike on a prison holding African migrants to 68 people killed. The rebels’ Civil Defense organization separately said 47 others had been wounded in the attack.
