Tehran: Iran on Wednesday said it had carried out and "concluded" its reprisal over the killing of top Iranian commander Qasem Soleimani when it targeted US forces in Iraq with a missile strike.
"Iran took and concluded proportionate measures in self-defence" targeting a base from which a "cowardly armed attack against our citizens and senior officials" was launched, said Foreign Minister Mohammad Javad Zarif on Twitter.
"We do not seek escalation or war, but will defend ourselves against any aggression,” the Minister added. Iran's Revolutionary Guards too have warned the US that any retaliatory measures would draw a renewed response.
A senior official in supreme leader Ayatollah Ali Khamenei's office also added that the missile attacks on the US airbase had been the “weakest” of the Iranian revenge scenarios.
According to an Iranian state television, at least 80 "American terrorists" were killed in the attack. US helicopters and military equipments too were severely damaged.
'All is well,' tweets Trump
US President Donald Trump, in his first reaction after Iran's missile attack on two American bases in Iraq, insisted that "all is well" and promised to make a statement to the nation soon.
Shortly after the missile attacks, Trump tweeted, "All is well! Missiles launched from Iran at two military bases located in Iraq. Assessment of casualties & damages taking place now. So far, so good! We have the most powerful and well-equipped military anywhere in the world, by far! I will be making a statement tomorrow morning."
Trump's tweet came after his reported meeting with his national security team, including Secretary of State Mike Pompeo and Defence Secretary Mark Esper.
Meanwhile, the Democratic party leadership continued to blame Trump for the escalating tensions in the Middle East.
"What's happening in Iraq and Iran today was predictable. Not exactly what's happening but the chaos that's ensuing," former US vice president Joe Biden said, blaming the situation on Trump's decisions of withdrawing from the Iran nuclear deal and ordering the missile strike in which Iranian general Soleimani was killed.
"Some of the things he's (Trump) done and said in the meantime have been close to ludicrous, including threatening to bomb holy sites...I just pray to God as he goes through what's happening, as we speak, that he's listening to his military commanders for the first time because so far that has not been the case," the Democratic presidential contender said.
On Tuesday, Trump threatened Iran of dangerous consequences in the event of an attack from them.
"If Iran does anything that they shouldn't be doing, they are going to be suffering the consequences, and very strongly," he told reporters at the White House.
Prompted by the strong public backlash over Soleimani's killing on Iraqi soil, lawmakers in Iraq voted on Sunday to demand the removal of all foreign forces from the country.
Despite Iraq voting on Sunday demanding the removal of all foreign forces from the country, more than 5,000 US troops remain in Iraq still along with other foreign forces as part of a coalition that has trained and backed up Iraqi security forces against the threat of Islamic State militants.
Soleimani, a 62-year-old general, was Tehran's pre-eminent military commander and - as head of the Quds Force, the foreign arm of the Revolutionary Guards - the architect of Iran's spreading influence in the Middle East.
US officials have said Soleimani was killed because of solid intelligence indicating forces under his command planned attacks on US targets in the region.
