IRGC-linked university said targeted in IDF strikes on Tehran
A major explosion could be heard around 5 a.m. in Tehran, following other explosions that boomed earlier in the predawn darkness.
Authorities in Iran offer no acknowledgement of the attacks, which have become increasingly common as the Israeli airstrike campaign has intensified since they began on Friday.
The Israelis earlier warned they could strike a neighborhood south of Mehrabad International Airport, which includes residential neighborhoods, military installations, pharmaceutical companies and industrial firms.
Iranian news websites also report that Israel targeted the Imam Hossein University in eastern Tehran, which is linked to the Islamic Revolutionary Guard Corps.
