An Israeli attack on Tehran's Evin Prison on June 23 killed 71 people, according to a spokesperson for the Iranian judiciary said.

Israel killed more than 30 senior security officials and 11 senior nuclear scientists to deliver a major blow to Iran's nuclear ambitions, a senior Israeli military official said on Friday in summarizing Israel's 12-day air war with Iran.

Crowds gathered in Tehran wearing all black and waving Iranian flags as the country held a funeral for top military commanders and nuclear scientists killed during the 12-day war with Israel.
