A US- and Israeli-backed group operating aid sites in Gaza has pushed back the reopening of its facilities set for today, as the Israeli army warned that roads leading to distribution centres were “considered combat zones”, AFP reports.

The Gaza Humanitarian Foundation (GHF) closed its aid distribution centres after a string of deadly incidents near sites it operates that drew sharp condemnation from the United Nations.

The GHF said late on Wednesday that its facilities would not open at the regular time today, without clarifying when they would resume service.

“Our distribution sites will not open early tomorrow morning as in previous days due to ongoing maintenance and repair work,” it wrote on social media.“We will share information about opening times as soon as work is complete.”

The Israeli army warned against travelling “on roads leading to the distribution centres, which are considered combat zones”.

The GHF said it was working to make aid distribution “as safe as possible” and urged those travelling to its sites to “follow the routes designated” by the Israeli army.
