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.

Israel has decided to send a delegation to Qatar for talks on a possible Gaza hostage and ceasefire deal, an Israeli official said, reviving hopes of a breakthrough in negotiations to end the almost 21-month war.

The Israeli delegation didn't have a sufficient mandate to reach an agreement with Hamas, two Palestinian sources told Reuters.
