"The IDF struck the headquarters of the Iranian terrorist regime's Marine Industries Organization," the military said, adding the strike was part of a wave of attacks conducted overnight from Friday to Saturday.

"This headquarters is responsible for the research, development, and production of a wide range of naval weaponry, including surface and sub-surface vessels, manned and unmanned equipment, as well as engines and weapons."

Later on Saturday, the military said it had intensified strikes on Iran's military industries.

"I can now say that within a few days, we will complete attacks on all critical components of this industry," military spokesman Brigadier General Effie Defrin said in a televised briefing.

"This means we will destroy most of its military production capabilities, and it will take the regime a long time to rebuild them.

Since the start of the war on February 28, the joint US-Israeli attacks have also struck Iran's nuclear sites, including a uranium processing facility and a heavy water reactor.
