The IDF on Tuesday evening eliminated at least ten terrorists who tried to enter Israel through Zikim Beach.
Security forces were dispatched to the area in case there are additional terrorist infiltrators.
Residents of Zikim and Karmia had been instructed to lock their doors and stay in their homes for their protection, but were given the all clear at around 11:30 p.m..
The IDF stated that security forces "attacked a terrorist cell that attempted to penetrate into Israeli territory in the Zikim area by sea. Fighter jets attacked the military installation from which the terrorists came."
In a subsequent statement, the IDF Spokesperson's Unit said, "Earlier today, IDF naval forces located a Hamas terrorist cell exiting a tunnel on the Gaza Strip coast and attempting to infiltrate Israeli territory via the sea, near Zikim."
"Israeli Navy, IAF and ground soldiers struck the terrorists and thwarted their infiltration attempt. IDF fighter jets and naval soldiers struck the tunnel and weapons warehouse used by the terrorists in the Gaza Strip," the statement added.
"There is no immediate risk of an additional infiltration at the moment."
Earlier on Tuesday, the IDF acted on precise Israel Security Agency (Shin Bet) intelligence and killed a number of Hamas terrorist organization operatives, including Abed Alrahman, Deputy Commander of the Nuseirat Battalion, who took part in the Kibbutz Be'eri massacre.
The other two terrorists who were eliminated are Khalil Muhajez, Deputy Commander of the Shati Battalion, and Khalil Tatri, Deputy Commander of the Sheikh Radwan Battalion.
