The IDF said that a research and development complex used by the Islamic Revolutionary Guard Corps was among several sites targeted in overnight strikes by the Israeli Air Force in Tehran. The IAF struck key infrastructure used by Iran’s security forces and military apparatus.

The military noted that the R&D complex used an underground tunnel system to carry out its research and testing of ballistic missiles and other key aspects of weapons development and manufacturing. The site was at Imam Hussein University, the military university of the IRGC that also functioned as an emergency facility and a meeting spot for military officials and operations.

The IAF continued attacking key targets connected to the Iranian governing body in Tehran, damaging the headquarters of the Quds Force as well as other sites used to manufacture weapons and defensive systems.

“These strikes were conducted as part of the effort to deepen the damage to the core arrays of the Iranian regime,” the military said in a statement.

Iranian officials from Kerman province reported damage to two aircraft and part of a local airport. Meanwhile, Iran International, an Iranian opposition Persian-language outlet, reported that two central Iranian banks, Bank Melli and Bank Sepah, had been targeted in a cyberattack, shuttering their services.

Separately, the IDF issued evacuation notices to villages in southern Lebanon, with Lebanese media reporting strikes on villages in the area later on. The Israeli military said that in response to rockets fired toward Israel from Lebanon Sunday, it had attacked Hezbollah command centers and other key sites housing military infrastructure.

The IDF accused Hezbollah of embedding its military infrastructure in civilian population centers.

“The Hezbollah terrorist organization embeds terrorist infrastructure within civilian areas, thereby endangering the residents of Lebanon,” the IDF said in a statement. “The placement of launchers and the firing from civilian areas in Lebanon constitutes a deliberate and cynical exploitation of Lebanese civilians in order to advance Hezbollah’s terrorist objectives.”
