No causality caused in attacks, Gaza officials say. Separately, protests were held against Israel during the funeral of a Palestinian girl who was killed last December while her body was returned to authorities in occupied West Bank on Friday.
Israeli forces said on Saturday they launched several strikes against Hamas sites in Gaza in response to a "projectile" launched from the besieged coastal territory the night before.
"IDF fighter jets and aircraft struck several military targets in a Hamas compound in the southern Gaza Strip and underground structures in the northern Gaza Strip," the military said in a statement.
"The strike was conducted in response to the projectile that was launched from the Gaza Strip at Israeli territory," it said.
Security officials in Gaza said the strikes did not cause any casualties.
