Yemen’s Houthi rebels on Monday alleged a US airstrike hit a prison holding African migrants, killing at least 68 people. The US military had no immediate comment, the Associated Press reported.

Graphic footage aired by the Houthis’ al-Masirah satellite news channel showed what appeared to be dead bodies and others injured at the site in Yemen’s Saada governate, a stronghold for the Houthis.

The Houthi-run Interior ministry said about 115 migrants had been detained at the site. African migrants from Ethiopia and other nations risk crossing war-torn Yemen for a chance to work in neighbouring Saudi Arabia. The Houthis said 68 people had been killed. There was no immediate independent confirmation of the death toll.

The airstrike is likely to renew questions from activists about the American campaign against the Houthis, known as “Operation Rough Rider,” which has been targeting the rebels as the Trump administration negotiates with their main benefactor, Iran, over Tehran’s rapidly advancing nuclear program.

The US military’s Central Command, in a statement early Monday before news of the alleged strike broke, sought to defend its policy of offering no specific details of its extensive airstrike campaign. The strikes have drawn controversy in America over Defense Secretary Pete Hegseth’s use of the unclassified Signal messaging app to post sensitive details about the attacks.

“To preserve operational security, we have intentionally limited disclosing details of our ongoing or future operations,” Central Command said. “We are very deliberate in our operational approach, but will not reveal specifics about what we’ve done or what we will do.”

The five days of hearings at the international court of justice (ICJ) in The Hague have been given a fresh urgency by Israel’s decision on 2 March to block all aid into Gaza, but the hearing will focus on whether Israel – as a signatory to the UN charter – acted unlawfully in overriding the immunities afforded to a UN body.
