The Israeli military said it intercepted a rocket fired by Palestinian militants from the Gaza Strip on Sunday night in a rare attack punctuating months of relative calm.
Air raid sirens sounded in the southern Israeli city of Sderot.
The military said the Iron Dome missile defense system downed an incoming rocket. There were no reports of casualties, but Israeli media reported damage to a vehicle.
Sunday’s attack was the first case of rocket fire from the Palestinian enclave in nearly a month. In early July, Gaza militants fired three rockets toward Israel, resulting in no casualties.
Israel and Hamas have largely maintained an informal cease-fire agreement in recent months.
