Israeli airstrikes killed at least 38 Palestinians in Gaza, hospital officials told the Associated Press on Sunday, as Israel's military said it has struck over 100 targets in the embattled enclave in the past day.

Two Palestinian sources familiar with the matter said the Israeli delegation didn't have a sufficient mandate to reach an agreement with Hamas.

At least 32 Palestinians were killed in Israeli airstrikes on Sunday, with 29 deaths reported in Gaza City alone, according to hospital sources. The bombardment came as Israel signaled a willingness to resume indirect ceasefire negotiations with Hamas in Doha under growing global pressure.
