A total of 87 people were killed or missing under the rubble after an Israeli attack on Saturday on northern Gaza's town of Beit Lahiya, the Palestinian enclave's health ministry said in a statement on Sunday.
More than 40 others were injured, it added.
The Israeli military said they were checking the report.
It said the figures did not align with its own information, the precise munitions used or the accuracy of the strike, which it said was directed at a Hamas target.
Palestinian health officials said rescue operations were being hampered by the cut-off of telecommunication and internet services for a second day. Earlier in the day, the Gaza health ministry said Israeli military strikes killed 35 Palestinians across the enclave.
Since Oct. 7, 2023, Israel's military offensive in the Gaza Strip has killed at least 42,603 Palestinians and wounded 99,795, the Gaza health ministry said.
