The IDF carried out a strike on Gaza on Saturday, after four rockets were launched from the Strip at Israeli communities.
Hours after U.S. President Joe Biden ended his visit to Israel, Palestinian factions fired at southern Israel. One rocket was intercepted by the Iron Dome missile defense system and three others fell in open areas.
The military said its planes hit a Hamas rocket manufacturing site and an underground facility where rocket material was being made.
A spokesperson said the aim of the strike on the underground facility was to prevent Hamas from increasing its military strength through its weapon's production.
No group claimed responsibility for the attacks but the IDF said in a statement that the Gaza ruling Hamas is responsible for any aggression from the Strip.
A Hamas spokesperson said Israel 's actions were criminal and causing terror in the hearts of Palestinians everywhere.
The group also condemned the announcement on Friday, that Saudi Arabia will allow Israeli flights to use its airspace.
"We are deeply saddened," the spokesperson said.
"The attempts of the American government to newly fabricate the region through involving the state is Israel, providing it with security by creating alliances between it and the Arab governments, will fail - because the nations' stance in the same countries resists these alliances," Hamas political leader Ismail Haniyeh said.
"The Palestinian nation will never again fall to the illusions of negotiations that harmed the Palestinian issue. Our choice is to continue resisting until the occupation ends," he said.
Ynet's security analyst Ron Ben Yisahi said that Hamas waited for Biden to arrive in Saudi Arabia before demonstrating their military opposition and avoided attack's while he was in Israel in order not to anger Egypt and suffer the wrath of an Israeli response, that would include suspending workers' permits to enter the country for work.
