Rocket sirens are triggered in cities throughout southern Israel, as well as in the town of Dimona, which is home to Israel’s main nuclear reactor.
Hamas’s military wing takes responsibility for the attack, saying it fired 15 rockets toward Dimona.
The alarms are heard in Ashkelon, Ashdod and up to Yavne to the north of the Gaza Strip and out to Beersheba and Dimona to the west of the enclave.
There are no immediate reports of injuries.
Residents of these areas report hearing the sounds of explosions overhead, indicating that at least some of the rockets were intercepted by the Iron Dome missile defense system.
