The Israeli military said it struck Hamas targets in the Gaza Strip early Sunday after two rockers were fired from the Palestinian territory.
In a statement, the military said fighter jets, attack helicopters and tanks hit Hamas underground infrastructure and military posts.
Two rockets were launched into Israel, with one reaching the southern Israeli city of Ashdod and the other stretching into central Israel, it added in a statement.
There were no immediate reports of injuries on either side, according to The Associated Press.
Israel said the rockets landed in open areas. Meanwhile, there was no immediate comment from Hamas officials.
Israel and Hamas have fought three wars and several smaller skirmishes since 2007.
A number of Palestinian militant groups operate in Gaza, but Israel holds Hamas responsible for all attacks and typically responds to rocket fire with airstrikes on militant targets.
