Democrats in the US have raised concerns that the Trump administration could 'bumble' into a war with Iran.
Republicans and Democrats met at the White House yesterday, after Iran shot down a US military surveillance drone.
Iran has insisted the unmanned aircraft was over its airspace, while the US claims it was over international waters.
Iran's foreign minister last night claimed the country had retrieved sections of the aircraft in Iranian territorial waters:
At 00:14 US drone took off from UAE in stealth mode & violated Iranian airspace. It was targeted at 04:05 at the coordinates (25°59'43"N 57°02'25"E) near Kouh-e Mobarak.

Overnight reports from US media outlets claimed President Trump 'abruptly' pulled back from plans to launch military strikes against Iran in retaliation for the downing of the drone.
The New York Times first reported the details, saying plans had been approved for strikes against targets such as radar and missile sites.
However, it was reportedly called off while the operation was in its early stages and before any missiles had been fired.
'Very big mistake'
Yesterday, President Trump said Iran made a "very big mistake" in shooting down the drone.
However, he also suggested it could have been done by someone being "loose and stupid".
Speaking at the White House, he said: "I have a feeling... that it was a mistake made by somebody that shouldn't have been doing what they did."
He also noted that he found it "hard to believe it was intentional".
Meanwhile, Democratic House Speaker Nancy Pelosi said the US shouldn't be reckless in its response - insisting there's "no appetite for war" in the country.
Senate minority leader Chuck Schumer warned that congressional approval is needed before funding any conflict.
He said: "I told the president that these conflicts have a way of escalating.
"The president may not intend to go to war here, but we're worried that he and the administration may bumble into a war."
While there have long been tensions between Iran and the US, relations have worsened in the wake of Donald Trump's decision to withdraw from the Iran nuclear deal.
The most recent tensions have arisen in the wake of attacks on two oil tankers in the Gulf of Oman last week.
The US has blamed Iran for the attacks, while Tehran has denied involvement.
