At least 14 civilians died after two houses were attacked in Gaza City, in the north of the territory, the official Wafa news agency reported.
Numerous deaths, including children and women, were also reported in a similar incident in the nearby Jabalia refugee camp, where an unknown number of people lie under the rubble, the news agency said.
A young man was also killed in the Tal al-Zaatar area after being shot by an Israeli sniper.

The battered city of Khan Yunis, the epicenter of a ground offensive, was the target of new attacks this morning, particularly the districts of al-Masri, Sarhan and al-Manara.
Gunboats in turn opened fire with heavy machine guns on the town of Rafah in the south of the coastal enclave.
Wafa warned of the serious crisis at Kamal Adwan Hospital, which was besieged by members of the neighboring country's armed forces for eight days.
The military has completely destroyed the southern part of the medical center and continues to attack anyone who moves there, he warned.
The source recalled that in recent weeks Israeli troops have raided several hospitals in the northern region of the Gaza Strip, also detaining doctors and sector workers there.
