The Gaza Humanitarian Foundation said on Saturday that two American aid workers had suffered non-life-threatening injuries in a grenade attack at a food distribution site in Gaza. The U.S.- and Israeli-backed GHF said in a statement that the injured Americans were receiving medical treatment and were in a stable condition.

A controversial aid operation for Gaza backed by Israel and the US says two of its workers have been injured in an attack while giving out relief. Two militants threw grenades at the aid centre in Khan Younis, the Gaza Humanitarian Foundation (GHF) said. It blamed Hamas for Saturday's incident.

Palestinians say they have no choice but to go to deadly US- and Israeli-backed aid sites amid growing starvation.
