"It was a very violent night, during which the (Israeli army) carried out dozens of air strikes and artillery shelling on Gaza City and other areas in the Strip, despite President Trump's call to halt the bombing," civil defence spokesman Mahmud Bassal told AFP.

Bassal, whose agency is a rescue force which operates under Hamas authority, added that 20 homes were destroyed in the overnight bombardments.

Gaza City's Baptist Hospital said in a statement that it received casualties from a strike on a home in the city's Tuffah neighbourhood, including four dead and several wounded.

Gaza's Nasser Hospital in Khan Yunis said two children were killed and eight people wounded in a drone strike on a tent in camp for displaced Gazans.

The peace plan for Gaza, presented by Trump this week and backed by Israeli Prime Minister Benjamin Netanyahu, calls for a ceasefire, the release of hostages within 72 hours, Hamas's disarmament and a gradual Israeli withdrawal from Gaza.

Hamas said on Friday it was ready to release hostages held in Gaza under the Trump plan but wanted negotiations on the details and a say in the future of the Palestinian territory.
