71 killed in Israeli attack on Iran prison, official says

Iran suffered damage in 12-day war, but damage to Israel was "far greater," Iranian President Masoud Pezeshkian said in an address Tuesday.

Pezeshkian acknowledged a ceasefire between Israel and Iran has been achieved after the 12-day war. The war was brought to an end "through the will and strength of the great Iranian nation," Pezeshkian said.

Pezeshkian said Israel failed in its objectives in the war, which were destruction of facilities, dismantling of nuclear knowledge and the incitement of social unrest. He said while Iran suffered losses -- loss of lives of its citizens and damage to Iran’s infrastructure -- Israel’s losses were far greater.

Iran was victorious in the war because of the "unity, calm and cohesion" of the Iranian people, Pezeshkian said.

Families of prisoners in Tehran's Evin Prison have been sharing accounts from their loved ones after a strike by the Israel Defense Forces on Monday damaged parts of the prison.

While the Monday strike was described in some reports as "symbolic," the Iranian judiciary news agency confirmed that "parts of the prison have been damaged."

A video published Tuesday by Iranian Tasnim News Agency shows a damaged area of the prison. Fars News agency reported that a doctor at the prison clinic was killed.

Evin is the largest prison in Iran for political prisoners and crimes related to national security in the country. There have been reports of human rights violations, including torture and forced confessions at the facility. It is not exactly clear how many inmates were inside the facility at the time of the strike, nor the number of injured or killed.

Israeli Defense Minister Israel Katz said Israel will "respect the ceasefire -- as long as the other side does," in a post on X Tuesday.

Katz spoke with U.S. Secretary of Defense Pete Hegseth Tuesday, thanking Hegseth for the U.S.’s "bold decision to stand with Israel against the Iranian nuclear threat," Katz said in the post.

Hegseth praised Israel for the "historic achievements made," Katz said in the post.
