The Israeli air force targeted a Hamas military training facility in central Gaza overnight on Sunday in response to a rocket attack, the army said.
A rocket was fired from the Gaza Strip on Sunday night and struck southern Israel with no reports of casualties or damage, the Israel Defence Forces said on its official Twitter account.
About 30 rockets, fired from the Palestinian enclave controlled by the Islamist group Hamas, have struck Israeli territory since the end of the Gaza war in 2014, according to the Israeli army.
Sunni militant groups claiming ties with ISIS say, they have been behind several rocket attacks in recent months, but Israel holds Hamas responsible for all such incidents.
