SANAA, Yemen (AP) — Yemeni security officials say a blast has struck a bus carrying air force personnel in a main street in the capital, causing casualties.
They say at least 20 people were wounded or killed in the explosion on Sunday in Sanaa. It was not clear how people many were on board.
The officials spoke anonymously as they were not authorized to talk to the media.
Bodies and blood could be seen on the pavement next to the remnants of the bus.
Yemen's government is battling militants linked to al-Qaida, who regularly target the country's military.
