Iran carried out a missile attack on the United States’ Al Udeid Air Base in Qatar on Monday, according to a U.S. official, two days after the U.S. struck three nuclear sites in Iran.

There are no reports of casualties at the base, according to a U.S. official.

Iran's attack was in response to the U.S. on Saturday sending B-2 bombers to drop 14 Massive Ordnance Penetrator bombs -- known as "bunker busters" -- over Iran. President Donald Trump on Sunday said that "Monumental Damage was done to all Nuclear sites in Iran," though Chairman of the Joint Chiefs of Staff Gen. Dan Caine said a full battle damage assessment is still pending.

No Americans hurt, 'hardly any damage was done' at US base: Trump

No Americans were hurt and "hardly any damage was done" by Iran’s "very weak" and "expected" missile attack on the United States’ Al Udeid Air Base in Qatar on Monday, President Donald Trump wrote on Truth Social, adding that the attack was "very effectively countered."

Trump said Iran fired 14 missiles. He said "13 were knocked down, and 1 was ‘set free,’ because it was headed in a nonthreatening direction."

Trump said Iran has "gotten it all out of their ‘system,’ and there will, hopefully, be no further HATE."

"I want to thank Iran for giving us early notice, which made it possible for no lives to be lost, and nobody to be injured," Trump continued. "Perhaps Iran can now proceed to Peace and Harmony in the Region, and I will enthusiastically encourage Israel to do the same."

DOJ has 'countless' open cases of threats to US homeland, Bondi says

The Justice Department currently has "countless" open investigations into threats to the U.S. homeland, Attorney General Pam Bondi said Monday in testimony to lawmakers on the House Appropriations Committee.

When asked about the presence of potential Iranian "sleeper cells" being activated in the U.S. in the wake of the military's strikes on Iran's nuclear program, Bondi said she couldn't answer such a question in an unclassified setting.

"I can't talk about that in this setting but what I can tell you is I know Homeland Security, I know the FBI -- they are focusing on doing everything we can to keep our nation safe, and they will continue to do that," Bondi answered. "Yeah, it's a frightening time in which we live right now, but President Trump is committed to keeping all Americans safe, and we look forward to working with you on that."

Bondi further confirmed that the department believes "well over 1,000" Iranian nationals entered the country illegally over the "last several years" and the department is on "high alert" regarding any potential illegal activity by those in the U.S.
