The Israeli army said in a statement that "in response to rocket fire from Gaza at Israel last night, IAF aircraft targeted a weapons manufacturing site in the central Gaza Strip overnight."
A hit was confirmed, the statement added.
Israeli radio said that projectiles had been fired at the Shaar HaNegev regional council in southern Israel.
The shelling in Gaza caused a fire to break out which fire fighters managed to extinguish. No injuries have been reported.
Earlier on Monday evening Israeli jets dropped flare bombs in the area, a Ma'an correspondent said.
