The military said fighter jets and other aircraft hit the weapons manufacturing site and “underground infrastructure” belonging to the Islamic militant group Hamas, which rules Gaza.
Late Thursday night, Palestinian militants fired two rockets at Israel. One was intercepted by Israeli missile defenses while the other fell into an open area.
Israel and Hamas have fought three wars and numerous skirmishes since the militant group wrested power from rival Palestinian forces in 2007. Israel has blamed Hamas for all attacks emanating from Gaza, including those claimed by other terrorist groups.
Israel and Egypt have maintained a dangerous blockade on the coastal region, home to 2 million Palestinians, since Hamas captured power.
Earlier this week, Israel announced the discovery of an unfinished tunnel dug by the terrorists, which crossed into Israel before it was detected by underground sensors. It said that the tunnel ran dozens of underground meters (yards) and was intended to facilitate the attacks.
Israel has revealed about 20 such tunnels since the last war with Hamas in 2014.
