Talks are under way to end the latest violence between Israel and Palestinian militants, which has killed at least 36 Palestinians since Friday.
Islamic Jihad militants and Israel are reported to have agreed a truce brokered by Egypt, but officially talks are still in progress.
Earlier, rockets fired from Gaza reached Jerusalem for the first time since May last year.
Israel says it launched strikes due to an “immediate threat” from militants.
The latest violence is the most serious flare-up between Israel and Gaza since an 11-day conflict in May 2021 left more than 200 Palestinians and a dozen Israelis dead.
However, the violence has so far been more limited as Hamas – the Islamist group that rules the Gaza Strip and which often coordinates with PIJ – has refrained from joining attacks against Israel. Israel says the PIJ has fired hundreds of rockets in recent days, most of which have been intercepted. No injuries have so far been reported in Israel.
There are no reports of Israeli air strikes targeting Hamas, which would mark an escalation in the violence.
Large crowds gathered on Sunday for the funerals of those killed in strikes on Rafah, in the south of the territory, including senior PIJ commander Khaled Mansour – the second top militant to have died. Demonstrations in support of Gaza have also been held in the West Bank city of Nablus.
On Sunday evening, the Palestinian health ministry said that 11 children were among the 36 deaths recorded so far.
Reports of a potential ceasefire deal come amid concerns over the humanitarian situation in Gaza, as health officials warned that hospitals only had enough fuel to run generators for another two days.
