The ceasefire between Israel and Hamas is over as Israeli fighter jets began striking the Gaza Strip after Hamas refused repeated hostage deal offers, officials said.

The military action comes as Prime Minister Benjamin Netanyahu's office accused Hamas of failing to return hostages, which was part of an increasingly fragile ceasefire agreement.

DEIR AL-BALAH, Gaza Strip — Israel launched new strikes against Hamas and promised "increasing military force" after talks on further hostage releases stalled, Israel's Office of the Prime Minister said Monday.
