Israeli forces carried out a number of attacks on Gaza overnight on Sunday and Monday, including on the Al-Mawasi camp near the southern city of Khan Younis, where at least 11 Palestinians were killed.
The attack reportedly took place on a so-called safe zone in Al-Mawasi, where scores of Palestinians had sought shelter.
Two victims were children, according to the Nasser medical complex, while the initial death toll was reported to be seven.
The attack led to a number of tents housing displaced Palestinians being set on fire.
On Monday, an Israeli drone attack targeted a vehicle in Khan Younis, killing those inside.
Israel also targeted the Nuseirat refugee camp on the same day. According to Al Jazeera, Israeli quadcopters and forces in armoured vehicles surrounded a school-turned-shelter in the area, shooting at it.
At least one person has been killed, Palestinian media said.
Four others were killed in a separate attack on an area northwest of the camp, while three others were injured, according to reports.
Meanwhile in Syria, the leader of its interim government, Ahmed Al-Sharaa, is set to meet with Jordanian foreign minister Ayman Safadi, one day after holding talks with Turkey's top diplomat, Hakan Fidan.
This is the first visit by a senior Jordanian official since Assad's fall.
The Jordanian foreign ministry said in a statement that Safadi would meet with the new Syrian leader on Monday as well as with "several Syrian officials" in the capital Damascus.
