SANAA, Yemen (AP) — Yemeni medical and military officials say a government warplane has mistakenly bombed an army position in the country’s south, killing at least 30 soldiers.

The officials said on Sunday that the bombing took place on Saturday evening in the southern Abyan province amid fighting with militants.

The officials say the soldiers of the army’s 119th brigade were stationed at an abandoned school just outside the capital of Abyan province, Zinjibar. Militants linked to al-Qaida control Zinjibar.

The officials spoke on condition of anonymity because they were not authorized to release the information.
