71 killed in Israeli attack on Iran prison, official says

Iran won’t violate the ceasefire unless Israel does, Iranian President Masoud Pezeshkian said Tuesday, according to Iran’s state-run media.

Pezeshkian made the comments in a telephone conversation with the prime minister of Malaysia Tuesday, Tasnim, Iran’s semi-official news agency, reported.

When Israel "failed to achieve its objectives, the U.S. directly participated in anti-Iran crimes and, contrary to all international rules, attacked Iranian nuclear sites," Pezeshkian said, according to Tasnim.

The Iranian attack on Al Udeid Air Base, the U.S. military site in Qatar, was "one of the most distressing consequences," of Israel’s "military aggression" against Iran, Pezeshkian told UAE President Mohammed bin Zayed Al Nahyan on Tuesday, IRNA, Iranian state-run media, reported.

Iran was compelled to respond to the "U.S. crimes" by attacking an American airbase in Qatar, Pezeshkian said. This does not mean Iran is in conflict with the Qatari government and people, he said, according to Tasnim.

Drones unsuccessfully targeted some U.S. military bases in Iraq Monday night and there were no American casualties, a U.S. official confirmed to ABC News.

The House and Senate will both receive separate classified briefings on the Iran-Israel conflict Tuesday afternoon.

The briefings are expected to include National Intelligence Director Tulsi Gabbard, CIA Director John Ratcliffe, Joint Chiefs of Staff Chairman John Caine, Deputy Secretary of State Christopher Landau and Deputy Defense Secretary Steve Feinberg, sources told ABC News.

Lawmakers, especially Democrats, will be looking for answers and evidence at the briefings from the administration, specifically why President Donald Trump said there was an imminent threat and carried out U.S. strikes on Iran’s nuclear sites.

Speaker of the House Mike Johnson said late Monday he expects the House briefing to have a different "tone" in the light of the ceasefire. Though, the events overnight will likely raise even more questions from members of Congress.

President Donald Trump and Israeli Prime Minister Benjamin Netanyahu spoke on Tuesday morning following Trump's post on social media warning Israel not to resume attacks on Iran, multiple sources familiar with the phone call told ABC News.

Trump "was exceptionally firm and direct" with Netanyahu about what needed to happen to sustain the ceasefire, one White House source said. "The prime minister understood the severity of the situation and the concerns President Trump expressed."

Netanyahu's office said Israel refrained from further attacks, but "In response to Iran's violations, the Air Force destroyed a radar array near Tehran," which would explain the reports of explosions in Iran. Israel alleged that Iran launched a barrage of missiles shortly before the ceasefire went into effect.
