A Huthi-run court in Yemen has sentenced 13 people to public execution on homosexuality charges, a judicial source said Tuesday, as human rights groups decried a rise in abuses by the Iran-backed rebels.

The sentences were handed down in Ibb, a province controlled by the Huthis whose attacks on Red Sea shipping since November have prompted retaliatory strikes by the United States and Britain.

Three others were jailed on similar charges, according to the judicial source, who spoke to AFP on condition of anonymity because he is not authorised to speak to the press.

Another 35 people have been detained by Huthis in Ibb province on homosexuality charges, the source said.

Videos shared with AFP, which could not be independently verified, showed a judge in a court reading out the death sentences on Sunday.
