Speaker Nancy Pelosi said she'd return a phone call to Vice President Mike Pence Tuesday night after he called to inform her about the Iranian missile attacks on U.S. targets in Iraq.

Pelosi was in a meeting with House Democrats when she was handed a note that Pence was on the phone. She responded: 'Tell him I'll call him back,' Politico reported.

Two minutes later, she was handed note that Iran attacked two bases in Iraq that housed American troops in retaliation for the U.S. killing General Qassem Soleimani.

'Pray,' she told lawmakers.

President Trump asked Pence to call congressional leaders about the attack

Later Tuesday night Pelosi was spotted at the opening of a new Italian restaurant in D.C.

Her spokesperson said the speaker returned Pence's call after she presided over the opening of the House of Representatives, which was having its first meeting since the start of the new year.

'@SpeakerPelosi returned a phone call to @VP at 6:34 p.m. tonight after her required presiding over the House at 6:30 p.m. The Vice President briefed the Speaker on the Iranian attacks on facilities housing U.S. troops in Iraq,' Pelosi's spokesperson Drew Hammill wrote on Twitter.

The House took a quorum call to assess there were enough lawmakers present to formally open the second session of the 116th Congress. The vote is a required procedure to begin the new legislative year.

President Donald Trump had asked Pence to call congressional leadership and inform them of the raid.

'Vice President Pence was briefed on Iran's attacks on bases hosting U.S. military and coalition forces in Iraq. The VP has been in continuous contact with the entire national security team and, at the President's direction, VP Pence completed calls to Congressional leadership,' Pence's spokesperson Katie Waldman tweeted.

Later Tuesday night, however, Speaker Pelosi was spotted at the opening of Maialino Mare - a Roman-style trattoria that held its grand opening in the hipster Navy Yard neighborhood of Washington D.C.

A food editor spotted the speaker at the event and posted a photo of her on Twitter but noted Pelosi was only there for 10 minutes.

Iran's Islamic Revolutionary Guard Corps fired 22 ballistic missiles at the Ain al-Asad airbase in western Iraq and Erbil International airport in the north part of the country in the early hours of Wednesday, but failed to kill a single U.S. or Iraqi solider, according to initial reports.

The attacks mark a significant escalation in the tit-for-tat blows exchanged between the U.S., Iran and their allies since last summer - but falls far short of fatal strikes on commanders and troops that had been feared.

Ayatollah Ali Khamenei, speaking on Iranian TV shortly after the missiles were launched, described the strikes as 'a slap in the face' of the United States and said they are 'are not sufficient (for revenge)'.

President Trump met with his national security team at the White House on Tuesday evening and delivered an upbeat message on the situation.

'All is well!' he wrote on Twitter. '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!'

He will make a statement at the White House at 11 a.m.

The timing of the Iranian strikes - around 1:20 a.m. local time - occurred at the same time as the U.S. drone strike last week that killed Soleimani.

Following the strikes, the Islamic Revolutionary Guard Corps warned any further strikes by America would be met with fresh attacks, and that any allied countries used as a base for such strikes would themselves become targets.

The Ain al-Asad airbase in western Iraq and the Erbil base in Iraqi Kurdistan were both struck by the missiles on Tuesday at about 5:30 p.m. (EST)

The Iraqi military said 22 missiles were fired in total - 17 at the Asad base, two of which failed to explode, and five more that struck Erbil International Airport. U.S. officials put the total slightly lower at 15 - ten of which hit Asad, one which hit Erbil, four which failed in flight.

Iran said it had used Fatteh-110 ballistic missiles for the attack, though analysts said images of wreckage near the Aasd base also appears to show Qaim-1 ballistic missiles were used.

Iran's foreign minister Mohammad Javad Zarif said Iran 'took and concluded proportionate measures in self-defence', but warned that his country will 'defend itself against any aggression'.

'We do not seek escalation or war, but will defend ourselves against any aggression,' he tweeted.

The Ain al-Asad airbase in western Iraq - visited by Trump in December 2018 - and Erbil base in Iraqi Kurdistan were struck by the missiles around 5:20 p.m. EST Tuesday in an operation dubbed 'Martyr Soleimani' by Iran.

The Pentagon said the missiles were 'clearly launched from Iran' to target U.S. military and coalition forces in Iraq.
