CNN:

President Donald Trump abruptly called off military strikes against Iran on Thursday night after previously approving the strikes in retaliation for Iran shooting down a US military drone, The New York Times reports.

The operation was already underway in its initial stages -- ships were in position and planes were in the air -- but no missiles had been fired when the order came to stand down, a senior administration official told the Times. The strike had been scheduled for just before dawn on Friday in Iran to minimize the risk to civilians and the Iranian military, and military officials received word shortly after then that the strike was off, at least temporarily.
 
The United States remains locked in a standoff with Iran, with US military or diplomatic responses having the potential to provoke further escalation from Tehran. Iran's downing of a US drone earlier Thursday has left the President caught between Republicans demanding a response and congressional Democrats warning that Trump -- and the Iran policy hardliners on his national security staff, who welcome the confrontation -- could lose control of the situation and lead the US into war.
 
Military and diplomatic officials were expecting a strike as late as 7 p.m. on Thursday after intense debate among Trump's top national security officials and congressional leaders at the White House, multiple senior administration officials involved in or briefed on the deliberations told the Times.
 
Trump initially approved attacks on a handful of Iranian targets, like radar and missile batteries, and the Times reports it was not clear whether Trump simply changed his mind or whether his administration pulled back because of strategy or logistics. It was also not clear whether the attacks may still occur.
 
The Times reporting drew swift reaction from Trump's Democratic rivals.
