Palestinian media outlets reported on Friday night that the strikes targeted positions belonging to the Palestinian resistance movement Hamas.
There have been no immediate reports on the extent of the damage and possible casualties due to the aerial aggression, which was jointly carried out by Israeli jets and combat drones.
The Israeli military claimed in a tweet that "striking Hamas targets" were in response to "a rocket" that "was fired from Gaza" at the occupied Palestinian territories earlier in the night, adding that "thousands of Israelis" were "currently in bomb shelters."
Israeli media outlets also reported that the "projectile" from Gaza landed in an open area in the vicinity of Sha'ar Hanegev in the southern occupied territories, without causing damage or casualties.
However, they added that it triggered sirens and the first red alerts in weeks in the southern city of Sderot and several other communities along the Gaza Strip.
