JERUSALEM (AP) — The Palestinian militant group Islamic Jihad said Thursday it had agreed to halt a wave of rocket fire on Israel, signaling an end to the heaviest fighting between the sides since 2012, though soon after the announcement seven rockets fired from Gaza exploded inside Israel.

The Islamic Jihad denied it launched the attack and it wasn’t immediately unclear who fired the rockets. Cease-fire declarations have not always been honored by militants and the barrage raised doubts about the cease-fire offer made by Islamic Jihad.
