Israel on Wednesday carried out its first airstrike in more than a week in Gaza, both sides said, breaking a relative lull as the United States pressed a peace plan.
Gaza's civil defence agency said the strike in Beit Lahia in the northern Gaza Strip targeted civilians riding in a tuk-tuk.
The strike killed Mohanad Saada, whose body was "torn to pieces", and wounded five other people, according to the civil defence agency and Al-Shifa Hospital.
A witness said Saada was among a group of workers who were repairing a wall damaged by Israeli shelling.
In Khan Younis, an elderly man and a child were injured after an Israeli drone dropped a grenade on a gathering of civilians, a medic at Nasser Hospital said.
"It is true that Israeli airstrikes and assassinations had almost completely ceased for over a week, but today the occupation resumed its aerial bombardment," civil defence spokesman Mahmoud Bassal told AFP.
The Israeli military claimed it targeted a Hamas commander, charging that he had been planning attacks against Israeli forces occupying the devastated territory.
Israel had not carried out airstrikes in the Gaza Strip since 3 August, following US President Donald Trump's announcement of a "major milestone" in his plan to end the war.
Hamas had announced that it would disarm by giving its weapons to a nascent Palestinian governing committee. Trump's "Board of Peace", in charge of implementing the ceasefire deal, had initially announced that Israel in turn would start a phased withdrawal from much of the Gaza Strip.
But Prime Minister Benjamin Netanyahu on Sunday publicly rejected the deal and vowed no Israeli pullout, even after the Board of Peace reassured him that Israel would not have to withdraw until complete Hamas disarmament.
Netanyahu, who faces pushback from his far-right base on Gaza ahead of tight elections in October, had until Wednesday avoided major strikes though Israeli forces have continued to shell areas of Gaza close to the line of contact.
Israel has refused to comply with the US-backed ceasefire in October, and has continued to launch daily attacks on the territory.
Israeli operations in Gaza have killed 1,259 Palestinians and injured more than 4,000 others since the ceasefire was supposed to come into effect, according to the local health ministry.
