US-Israeli strikes hit at least three locations across Tehran on April 3, including Shahid Beheshti University, one of Iran's largest academic institutions, the area around Mehrabad airport and the Telou district, IRIB reported.

A research and teaching building at Shahid Beheshti University in the Velenjak neighbourhood of northern Tehran was struck at 4:02pm local time, Mehr News Agency reported. No deaths were reported but a number of university staff were injured by the blast wave.

The strike on a major university comes after Iran's foreign ministry condemned the bombing of the Pasteur Institute on April 2 as "beyond a war crime." China's foreign ministry spokesperson said on the same day that attacks on schools were "an egregious violation of international humanitarian law."

Iran's Ministry of Science said that as of April 1, 154 sites across 21 universities and higher education institutions under its supervision had been damaged since the war began on February 28. Total damage to academic infrastructure has been estimated at more than IRR4tn ($95mn at free market rates).

The strikes on Mehrabad, Tehran's domestic airport and a military airfield, and the Telou district in eastern Tehran were also confirmed by state media, though details of damage and casualties at those locations were not immediately available.

Tehran has come under repeated overnight and daytime bombardment since the start of the conflict, with strikes hitting at least four municipal districts on March 31 and the chamber of commerce headquarters on April 1.

Iran's Ministry of Health has reported more than 2,076 people killed since the war began, including 216 children.
