Palestinian militants in the Gaza Strip fired at least 130 rockets into southern Israel, the Israeli military said. No immediate casualties were reported.
The military said its “Iron Dome” defence system intercepted at least three rockets, while the others fell in open areas.
Israeli police spokesman Micky Rosenfeld said one rocket exploded near a gas station and another near a public library.
Police raised the level of alert in the south, saying the rockets struck along the length of Israel’s border with Gaza.
