Israeli aircraft bombed several terror target sites in Gaza early Sunday, hours after three rockets were fired from the Palestinian enclave toward southern Israel.
The military said in a statement the airstrikes targeted several Hamas posts and a naval base. There were no immediate reports of casualties.
On Saturday evening, the IDF said the Iron Dome defense system intercepted the projectiles fired from the Gaza Strip.

No Palestinian group claimed responsibility for the rocket fire.
Israel maintains that Hamas, as the group ruling Gaza, is responsible for any rocket fire from the Strip.
On Friday, thousands of Palestinians demonstrated along the Gaza-Israel border.
The renewed weekly protests came as leaders from Hamas and the smaller but more radical Islamic Jihad were in Cairo, talking with Egyptian mediators about cementing a ceasefire with Israel that is expected to ease Gaza's 12-year-old blockade.
Organizers of the marches kept them restrained Friday, with no burning tires or firebombs, and with only a few protesters approaching the fortified perimeter fence and hurling stones at Israeli troops with slingshots.
Hamas' Health Ministry said 14 Palestinians were wounded by Israeli fire.
Hazem Qassem, a Hamas spokesman, said his movement is determined to break the blockade and that the talks in Cairo, which also include bilateral discussions with the Islamic Jihad, were for this purpose.
"We won't allow this situation to last and we will continue the protests until the siege is broken," he said in a statement.
Unconfirmed reports say Egypt has proposed a five-year truce that will see economic incentives to Gaza to sustain calm.
Meanwhile, in the West Bank, Israeli forces shot a 22-year-old Palestinian near the city of Hebron. The health ministry said the man was in serious condition after a live bullet hit him in the chest.
