Iranian forces launched more than a dozen ballistic missiles against two military bases in Iraq, the Pentagon said Tuesday evening, marking the most significant Iranian attack in the growing conflict with the United States.

The al-Asad air base in western Iraq, which houses some American troops, was hit by at least six missiles , according to a U.S. defense official familiar with the situation.

In a tweet late Tuesday, President Trump proclaimed “All is well!” and vowed to address the nation on the situation Wednesday morning.

The strike comes as U.S. officials have defended Trump’s decision to kill Maj. Gen. Qasem Soleimani, the commander of Iran’s elite Quds Force, in an airstrike in Baghdad last week. Iranian leaders stepped up calls Tuesday for revenge against the United States as Iranian authorities prepared to bury Soleimani in his hometown of Kerman, a southeastern city. Early on Tuesday, authorities were forced to suspend the burial proceedings after a stampede killed dozens of mourners.

Here’s what we know so far:

● Iranian forces have launched more than a dozen ballistic missiles against two military bases in Iraq.

● Secretary of State Mike Pompeo and Defense Secretary Mark T. Esper met with President Trump at the White House following the attack. The president said he will make a statement Wednesday morning.

● Esper said the United States will not be withdrawing troops from Iraq. The Trump administration is drawing up potential sanctions against Iraq, in the event that its leaders go through with plans to order the expulsion of U.S. troops for Soleimani’s killing on Iraqi soil.

● Iranian state news agencies reported that at least 50 people died and more than 200 were injured in the stampede at the funeral for Soleimani.
