A Palestinian died on Monday when a tunnel he was trying to restore collapsed near Gaza's border with Egypt, Palestinian medical and security sources said.

The death brings to 10 the number of Gazans killed in three separate tunnel collapses in two weeks.

The man was killed "as a result of a collapse of a mass of sand" inside a tunnel previously used to smuggle goods, a security source said.

He had been trying to restore the damage caused by Egypt flooding the tunnel, the source added.

A medical source identified him as Mussa Jaber al-Maadi, 24 and from Rafah in the southern Gaza Strip.
