Fewer rockets have been launched, but Israeli towns are still being hit.
Ninety-five Palestinians and three Israelis have died in six days of violence, the latest fatalities including a militant group commander.
Efforts to secure a ceasefire continue, with a senior Egyptian official saying there are "encouraging signs".
Khaled Meshaal, the political leader of the Islamist movement Hamas which controls Gaza, said Israeli Prime Minister Benjamin Netanyahu had requested a ceasefire but that it was up to Israel to stop the war that, he said, it had started.
Israel immediately denied making any such request, Reuters reported.
"Hamas's comments about a ceasefire, alleging that Israel is begging for one, are about as accurate as its claims to have shot down an F-15 [warplane] or attacked the Knesset," the agency quoted a senior government official as saying.
Mr Meshaal said that a truce was possible in Gaza - as was further escalation of the conflict.
