Gaza's Islamist rulers Hamas, along with an allied militant group, fired hundreds of rockets at Israel on May 4 and 5, saying they were frustrated by the slow implementation of a previous ceasefire deal.
A new agreement was brokered which reportedly includes tens of millions of Qatari aid to Gaza as part of a package to ease Israel's crippling blockade of the strip.
The Gulf state, a rare Hamas ally in the region, has been providing millions in aid to the strip monthly since November.
"This morning, the distribution of a cash aid of 100 dollars per poor family began," he said, adding it was destined for 108,000 families.
"The risk of war remains imminent and today we have perhaps the last chance to consolidate the agreements that have been reached," he told a press conference in Gaza.
"The next escalation is going to be probably the last." He said he had seen welcome steps by Israel in the wake of the latest uptick, such as extending the Gaza fishing zone and reopening border crossings.
The UN was preparing a series of projects to improve the lives of people in Gaza, he said.
Around 80 per cent of Palestinians in impoverished Gaza are reliant on international aid, according to the United Nations.
