Israeli airstrikes killed at least 33 Palestinians in Gaza, hospital officials said on Sunday, as Israel’s military said it has struck over 100 targets in the embattled enclave in the past day.

DEIR AL-BALAH, Gaza Strip — Israeli airstrikes killed 14 Palestinians in Gaza and another 10 were killed while seeking food aid, hospital officials in the embattled enclave told The Associated Press on Saturday, as U.S.-led ceasefire efforts appeared to gain momentum after nearly 21 months of war.

Israeli attacks on targets in the Gaza Strip have once again led to numerous casualties, Palestinian sources said on Saturday. Medical sources reported that since the early morning hours, at least 40 people had died in attacks in various parts of the sealed-off coastal area.
