Yemen’s Houthi rebels on Monday alleged a US airstrike hit a prison holding African migrants, killing at least 68 people and wounding 47 others. The US military had no immediate comment.

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 as a U.S. airstrike that killed 68 people.

The strike in Yemen's Saada governorate, a Houthi stronghold, is the latest incident in the country's decade-long war against African migrants who risk crossing Yemen for a chance to work in Saudi Arabia.
