Four people, two of them children, were killed in an Israeli air strike on a tent encampment on Monday in the coastal area of Al-Mawasi, designated as a humanitarian zone, while two others were killed in temporary shelters in the southern city of Rafah and another in drone fire, health officials said.
In Beit Lahiya town in northern Gaza, medics said an Israeli missile struck a house, killing at least two people and wounding several others.
On Sunday, medics and residents said dozens of people were killed or wounded in an Israeli air strike on a multi-floor residential building in the town.
The Israeli military, which has been fighting Palestinian militant group Hamas in Gaza since October 2023, said it conducted strikes on "terrorist targets", in Beit Lahiya.
Later on Monday, an Israeli air strike on a house in Gaza City killed five people and wounded 10 others, medics said.
There has been no Israeli comment on Monday's incidents.

The Israeli army sent tanks and soldiers into Beit Lahiya and the nearby towns of Beit Hanoun and Jabalia, the largest of the Gaza Strip's eight historical refugee camps, early in October in what it said was a campaign to fight Hamas militants waging attacks and prevent them regrouping.
Hussam Abu Safiya, the director of the Kamal Adwan Hospital in Beit Lahiya, said the hospital was under siege by Israeli forces and the World Health Organisation had been unable to deliver supplies of food, medicine and surgical equipment.
Cases of malnutrition among children were increasing, he said, and the hospital was operating at a minimal level.
"We receive daily distress calls, but we are unable to assist them due to the lack of ambulances, and the situation is catastrophic," he said.
"Yesterday, I received a distress call from women and children trapped under the rubble, and due to my inability to help them, they are now among the martyrs (dead)."
Israel said it had killed hundreds of militants in the three northern areas, which residents said was cut off from Gaza City, making it difficult and dangerous for them to flee.
The armed wings of Hamas and militant group Islamic Jihad said they had killed many Israeli soldiers in anti-tank rocket and mortar fire attacks during the same period.
The Hamas-run Gaza health ministry says more than 43,800 people have been confirmed killed since the war erupted on October 7, 2023.
Hamas militants killed about 1200 people in attacks on communities in southern Israel that day, and hold dozens of some 250 hostages they took back to Gaza, according to Israeli tallies.
