Israel-Iran updates: Israel and Iran agree to ceasefire, Trump says

The agreement has two 12-hour ceasefire periods before the war is over, he said.

Iran carried out a missile attack on the United States’ Al Udeid Air Base in Qatar on Monday, according to a U.S. official, two days after the U.S. struck three nuclear sites in Iran.

There are no reports of casualties at the base, according to a U.S. official.

Iran's attack was in response to the U.S. on Saturday sending B-2 bombers to drop 14 Massive Ordnance Penetrator bombs -- known as "bunker busters" -- over Iran. President Donald Trump on Sunday said that "Monumental Damage was done to all Nuclear sites in Iran," though Chairman of the Joint Chiefs of Staff Gen. Dan Caine said a full battle damage assessment is still pending.

Also on Monday, Trump announced that Israel and Iran have agreed to a ceasefire, after more than a week of aerial attacks following Israel's attack on Iran's nuclear program.

Gabbard calls Iran-Israel ceasefire a 'herculean effort' by Trump

Director of National Intelligence Tulsi Gabbard praised what she called a “historic" ceasefire agreement between Iran and Israel, crediting President Donald Trump with brokering the deal and calling it a “herculean effort.”

Gabbard had been at the White House in recent days as diplomatic talks intensified and airstrikes escalated, alongside senior staff and Cabinet officials.

Last week, Trump has expressed frustration with Gabbard's previous comments, saying she was "wrong" when she told Congress in March there was no evidence Iran was building a nuclear weapon.

As a 2020 Democratic candidate, Gabbard was adamant in her opposition to "regime change wars" and war with Iran, so much so that she sold campaign t-shirts that said, “No War With Iran.”
