Iran has launched more than a dozen ballistic missiles at two US military bases in Iraq.
The Al Asad airbase in western Iraq was targeted in the attacks, as well as a complex in the northern city of Erbil. Al Asad houses both Iraqi and US armed forces, with UK forces also frequenting.
The attacks serve as retaliation for the killing of top Iranian general Qassem Soleimani, who died in a US-directed strike last week.
Iranian Foreign Minister Javad Zarif believes that Iran has taken and "concluded" "measures in self-defence", indicating that the attacks are now over - unless the US strikes back.
There has been no official word on casualties.
A Ukrainian plane also crashed shortly after taking off from Imam Khomeini Airport in Iran's capital, Tehran. Roughly 180 passengers and crew on-board the aircraft have died.
Now, the world is waiting for US President Donald Trump to make a statement regarding the attacks - and what America's next move might be.

"What matters is that the presence of America, that is a source of corruption in this region, that should come to an end."
Iran's president Rouhani reportedly said during a cabinet meeting that Iran "will cut" America's presence in the region as they "cut the hands of Qassem Soleimani".

No casualties have been confirmed as of yet, with Trump saying initial assessments of damage and casualties are "so far so good". Canada, New Zealand, Australia and Norway have also confirmed that their military personnel are safe.
Following the reporter's aforementioned comments, Safi said this continues to indicate that Iran orchestrated the attack to ensure no casualties were sustained.
Safi said in this scenario, the strikes would've been designed "to satisfy its domestic audience that Soleimani's death had been publicly avenged" while also "providing room for the US not to respond and to de-escalate the conflict".

6:45pm - Iranian state media are reportedly claiming that the missile strikes caused at least 80 US casualties.
The Guardian reporter Michael Safi says this claim is "almost certainly not true" - but it allows Iran to "beat their chest and claim victory".
Safi insinuated, like many others, that the attacks may have been carefully orchestrated to avoid any US casualties. He also suggested that in the best-case scenario, the US may step back if there is no substantial damage or casualties - leading to the strikes becoming an "opportunity to de-escalate without losing face".
"Iran will say it took violent revenge for Soleimani's death and pivot to a campaign of proxy warfare - with which it feels more comfortable, against a vastly more powerful adversary - and diplomatic pressure to eject American forces from Iraq," Safi wrote.

"We do not want to cut and run unduly, leaving others to shoulder our responsibilities," Mitchell said.
"We have a proud history of operating in the Middle East to keep the peace and it's important that we are not distracted from our continued efforts to stabilise Iraq."
Brownlee said it is the time for "cool heads" and "meaningful dialogue" rather than "tit for tat retaliation".

"All I'd say is that we are as always very clear about our responsibility to maintain good situational awareness around security. We have stringent security measures in place in terms of force protection.

The Guardian reports a statement from IRGC: "The brave soldiers of IRGC’s aerospace unit have launched a successful attack with tens of ballistic missiles on Al Assad military base in the name of martyr Gen. Qassem Soleimani."
Iranian state television has also said Iran is behind the attack, having fired "tens" of missiles.
It is a time of high tension within the Middle East, following the death of Qassem Soleimani, the head of Iran's infamous Quds Force, in a United States-directed airstrike on Friday. Soleimani was regarded as one of Iran's most powerful people and his death has spurred threats of revenge from Iran's Supreme Leader Ayatollah Ali Khamenei.
Iran has vowed revenge for the attack, while US President Donald Trump has said the United States is targetting 52 Iranian sites that it will strike if Iran retaliates.
In late December, an America contractor in Iraq was killed in a rocket attack which the US blamed on Iranian-backed militia. In response, the US killed 25 Kataeb Hezbollah fighters, leading militias to attack the US Embassy in Baghdad.
Sticking to similar lines to what the Pentagon said in a statement following the airstrike, US Trump said on Saturday that the decision to strike was to "stop a war". Ravanchi, however, said it had started one.
"Soleimani was plotting imminent and sinister attacks on American diplomats and military personnel but we caught him in the act and terminated him," the president said.
Roughly 3000 additional soldiers are being sent to the Middle East following Friday's airstrike.
How Iran will respond, and when and where, is not known. The US Homeland Department says there are no current domestic threats but is on the watch for any cyber attacks.
Democrats have criticised Trump's direction to strike, saying it wasn't educated and was ordered without congressional permission. However, sources have told CNN there was a consensus within the president's national security cabinet that based upon intelligence, action was needed. Three sets of White House lawyers also vetted the plan and said Trump did not need authorisation.
