Live updates: Trump says 'very good' Iran talks, hints at 'total resolution'

More than a dozen unmanned MQ-9 Reaper drones have been lost in combat as part of the operations against Iran, two U.S. officials confirmed to ABC News.

The Reaper drones were either lost to Iranian missile fire or were destroyed on the ground by incoming fire.

Reaper drones can be used as reconnaissance aircraft, but they are also equipped with Hellfire missiles used to strike at targets.

The loss of this number of Reapers is indicative of how many of these key unmanned aircraft must be operating as part of the U.S. operations against Iran.

The loss of the drones in the Iran war was first reported by the Wall Street Journal.

Iran's Supreme National Security Council has confirmed that senior official Ali Larijani is dead.

In a statement published by the semi-official Tasnim news agency on Tuesday, the council said Larijani died alongside his son, a security deputy of the secretariat, and several members of his protection team. It did not provide details on how or where the deaths occurred.

Earlier Tuesday, the Israeli minister of defense said Larijani, the head of Iran's Supreme National Security Council, was killed in an overnight attack on Iran.

President Donald Trump said that "most of our NATO 'allies'" do not want to join the U.S. and Israel's war against Iran.

Trump claimed allies' refusal to join is "despite the fact that almost every Country strongly agreed with what we are doing, and that Iran cannot, in any way, shape, or form, be allowed to have a Nuclear Weapon," he wrote in a post on social media.

"Because of the fact that we have had such Military Success, we no longer 'need,' or desire, the NATO Countries' assistance - WE NEVER DID! Likewise, Japan, Australia, or South Korea .... WE DO NOT NEED THE HELP OF ANYONE!" he said in the post.

French President Emmanuel Macron said the country would never take part in operations to unblock the Strait of Hormuz, and that it is carrying on with work to prepare a coalition that could provide freedom of navigation once hostilities ended, according to Reuters.

"We are not party to the conflict and therefore France will never take part in operations to open or liberate the Strait of Hormuz in the current context," Macron said at the start of a cabinet meeting to discuss the conflicts in the Middle East, according to Reuters.

The Trump administration's top counterterrorism official Joe Kent announced his resignation Tuesday over opposition to the Iran war, becoming the highest-profile administration official to step down publicly over the conflict.

In a resignation letter posted publicly on social media, Kent said he could not "in good conscience" support the war, which is now in its third week.

"Iran posed no imminent threat to our nation, and it is clear that we started this war due to pressure from Israel and its powerful American lobby," Kent, who served as the director of the National Counterterrorism Center, wrote in his resignation letter.

The National Counterterrorism Center is housed within the Office of the Director of National Intelligence. ABC News has reached out to ODNI for comment.
