In pics: historic buildings in Old City of Sanaa destroyed in civil war

People walk on the rubbles of a historic building destroyed in an airstrike in the Old City of Sanaa, Yemen, on July 7, 2019. Many historic buildings in the Old City of Sanaa have been destroyed in a civil war between pro-government Yemeni forces and the Houthi rebels since the Houthi rebels overran much of the country militarily and seized all northern provinces in 2014.
