The IDF said as part of the recent waves of strikes completed in Tehran, the Israeli air force, guided by intelligence, targeted the facility, part of Malek-Ashtar University of Technology in Tehran. It claimed that the site was used by Iran's military industries and ballistic missile array to develop nuclear weapon components and weapons.

According to the MDA, seven people were seriously injured, 15 moderately injured, and the rest lightly injured. It added that searches continue at the scene to find more injured people. Israel's state-owned Kan TV News reported that it was a direct missile hit at a residential building, causing many casualties and extensive destruction. It added that emergency services have declared a "mass casualty incident," and army and MDA helicopters were rushed to the scene. According to the channel, the Israeli air force has launched an investigation to examine why the missile was not intercepted by the air defense system. Earlier in the evening, a missile fired from Iran injured 47 people in the southern city of Dimona, including a 10-year-old boy in serious condition, according to the MDA.

Iran fires missiles at US-British base in Indian Ocean Iran fired two ballistic missiles at the U.S.-British Diego Garcia military base in the Indian Ocean, the semi-official Mehr news agency reported on Saturday. The Wall Street Journal and the CNN reported on Friday that Iran had fired ballistic missiles at the base on the island of Diego Garcia, part of the Chagos Islands, but they did not hit the base. Britain agreed on Friday to allow the United States to use the Diego Garcia base to launch strikes on Iranian missile sites that are attacking ships in the Strait of Hormuz, according to the British media. The decision came after U.S. President Donald Trump said he was "very disappointed" in British Prime Minister Keir Starmer for blocking U.S. forces from using the military base to carry out strikes on Iran. Iran's FM says mediation efforts underway to end war Iranian Foreign Minister Seyed Abbas Araghchi has said mediation efforts are underway by several countries to end the U.S. and Israeli war against Iran. Araghchi made the remarks in a Friday interview with Japan's Kyodo News, published Saturday, while voicing Iran's openness to any initiative to that end. He said that Iran does not seek a ceasefire, "but a complete, comprehensive and lasting end to the war," reminding that the war has been "imposed" on Iran. The attacks began when Tehran was in the middle of nuclear negotiations with the United States, Araghchi said, adding that Iran's response to the U.S.-Israeli attacks constitutes self-defense and will continue for as long as needed. On the Strait of Hormuz, he said Iran has not closed the waterway, but has imposed restrictions on vessels belonging to countries involved in anti-Iran attacks. Araghchi said Iran is ready to ensure safe passage for other states' vessels through the Strait of Hormuz if they coordinate with Tehran.
