An American man identified as Steven Weber Jr died during an underwater proposal which went wrong this week in Tanzania.

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 underwater to ask Ms Antoine to marry him.

In the video according to the BBC report, 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.

“It is with the deepest regret that we inform that a fatal accident occurred at The Manta Resort on Thursday 19 September 2019,” the resort said in a statement.
