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

Graphic footage aired by the Houthi's al-Masirah satellite news channel shows what appears to be dead bodies and others wounded at the site in Saada.
