An American man has drowned while proposing to his girlfriend underwater on holiday in Tanzania. Steven Weber and his girlfriend, Kenesha Antoine, were staying in a submerged cabin at the Manta Resort, off Pemba Island. Footage shows Mr Weber diving under water to ask Ms Antoine to marry him. In the video, Mr Weber presses a hand-written proposal note against the cabin window as Ms Antoine films from inside. Ms Antoine, confirming Mr Weber's death in a Facebook post, said he "never emerged from those depths". The Manta Resort told the BBC Mr Weber "tragically drowned while free diving alone outside the underwater room" on Thursday afternoon.
