21 June 2019; AFP: Iran said Friday it had "indisputable" evidence a US drone it downed had violated its airspace, as reports emerged in the US that President Donald Trump had approved then scrapped retaliatory strikes against Iranian targets.
The downing of the drone -- which Washington insists was above international waters but Iran says was within its airspace -- has seen tensions between the two countries spike further after a series of attacks on tankers the US has blamed on Tehran.
Under pressure to respond to the high-stakes incident near the strategic Strait of Hormuz, Trump issued orders for retaliatory strikes on a limited number of Iranian targets, the New York Times reported.
The US was planning to hit "a handful of Iranian targets, like radar and missile batteries" Thursday evening, the newspaper said, citing senior administration officials.
"The operation was underway in its early stages when it was called off," one official said. "Planes were in the air and ships were in position, but no missiles had been fired when word came to stand down."
White House and Pentagon officials declined to comment, the Times said, and it was unclear whether Trump had decided to delay retaliatory strikes or cancel them altogether.
The US president had struck a combative tone in his public comments before rowing back.
"Iran made a very big mistake!" he tweeted in response to news Iran had shot down the Global Hawk surveillance aircraft.
"This country will not stand for it, that I can tell you," he said later at the White House.
But as the pre-dawn incident whipped up fears of open conflict between the United States and its declared foe Iran -- sending crude oil prices soaring -- Trump moved swiftly to dial back tensions.
"I find it hard to believe it was intentional, if you want to know the truth," Trump said. "I think that it could have been somebody who was loose and stupid that did it."
The president's mixed message left the world unsure what Washington's next move would be.
Oil prices edged down slightly Friday following the previous day's surge that saw prices soaring more than six percent.
Iran said Friday it had called in the Swiss ambassador, whose country has represented US interests since the severance of diplomatic relations in the aftermath of the Islamic revolution of 1979, to issue a formal protest.
Deputy foreign minister Abbas Araghchi provided the ambassador with "indisputable" evidence the drone had violated Iranian airspace, the foreign ministry said.
Araghchi "reiterated that Iran does not seek a war and conflict in the Persian Gulf", but warned: "The Islamic Republic of Iran would not hesitate for a moment to decisively defend its territory against any aggression."
Iranian television later broadcast images of what it said was "debris" of the downed drone recovered from Iran's territorial waters.
- Flights rerouted -
The US Federal Aviation Administration warned of danger to flights "demonstrated by the Iranian surface-to-air missile shoot-down of a US unmanned aircraft system", and barred American civilian aircraft from the area where it took place "until further notice."
Airlines including British Airways, Qantas and KLM said Friday they too were altering flight paths over the Middle East to avoid the sensitive Strait of Hormuz area.
"The incident with the drone is reason not to fly over the Strait of Hormuz for the time being. This is a precautionary measure," Netherlands carrier KLM said.
The Pentagon denounced the "unprovoked attack," claiming the navy drone was 34 kilometres (21 miles) from Iran when destroyed by a surface-to-air missile.
It published a map showing the flight path of the drone, which indicated it travelled outside of Iranian waters and included a photograph showing it was at the coordinates (25°57'42"N 56°50'22"E) when it was downed.
Zarif provided different coordinates for the downing of the drone by a domestically-manufactured Khordad 3 air defence battery.
"At 00:14 US drone took off from UAE in stealth mode & violated Iranian airspace," Zarif tweeted. "It was targeted at 04:05 at the coordinates (25°59'43"N 57°02'25"E) near Kouh-e Mobarak."
The drone downing came as Iran was already accused by Washington of carrying out attacks on tankers in the congested shipping lanes heading out of the Gulf through the Strait of Hormuz.
Tehran denies any involvement.
- Options 'running out?' -
Trump has repeatedly said he does not favour war with Iran unless it is to stop the country getting a nuclear weapon -- something Iranian leaders insist they are not pursuing.
But Trump critics say his policy of "maximum pressure" -- including abandonment of an international deal to regulate Iran's nuclear activities, crippling economic sanctions and deployment of extra troops to the region -- make war ever more likely.
One of Trump's biggest opponents, the Democratic speaker of the House of Representatives, Nancy Pelosi, warned that "there's no appetite for wanting to go to war in our country".
Russian President Vladimir Putin, who has close relations with Iran's leadership, said US military retaliation "would be a disaster for the region."
