Israeli warplanes raided south and central Gaza late Thursday, targeting sites belonging to Hamas, witnesses said.
There were no immediate reports of injury.
Airstrikes targeted a projectile launch site in southern Gaza, causing no injuries, and two bases belonging to Hamas’ Al-Qassam Brigades near Khan Younis and in Gaza City.
The attack on the site in Gaza City caused material damage and frightened residents.
An Israeli army spokeswoman confirmed the strikes but did not elaborate.
Earlier, reports said six projectiles were fired from Gaza since Thursday, causing no injuries.
Five people were injured a day earlier in a raid on the tunnel area in Rafah.
