Senior Pentagon officials revealed new details about the U.S. operation to bomb three nuclear sites in Iran, with the chairman of the Joint Chiefs of Staff saying it was the "largest B-2 operational strike in U.S. history" and inflicted "extremely severe damage and destruction" to the targets.

"This was a highly classified mission with very few people in Washington knowing the timing or nature of this plan," Gen. Dan Caine, the chairman, said in a briefing at the Pentagon Sunday morning detailing the strikes against the Iranian nuclear sites at Fordo, Natanz and Isfahan.

Caine said the mission, dubbed Operation Midnight Hammer, included seven B-2 Spirit bombers that flew east from their base in Missouri to Iran. The 18-hour flight required multiple in-flight refuelings, and the bombers met up with U.S. fighter jets and support aircraft once over land in the Middle East in a "complex, tightly timed maneuver," Caine said.

President Trump and Russian President Vladimir Putin met in Alaska on Friday for a high-stakes summit on ending the war in Ukraine, but the talks failed to produce the ceasefire that Mr. Trump had sought.

The two leaders, along with a pair of top aides each, met for nearly three hours at Joint Base Elmendorf-Richardson in Anchorage after a carefully choreographed welcome that included a red carpet and military flyover.

In brief remarks afterward, Putin alluded to unspecified "agreements," while Mr. Trump called the meeting "extremely productive." Neither leader, however, mentioned a halt to the fighting in Ukraine. The summit ended early without a planned meeting between a broader group of officials.

A federal judge on Monday ordered the criminal charges against former FBI Director James Comey and New York Attorney General Letitia James to be dismissed on the grounds that Lindsey Halligan, the interim U.S. attorney who secured their indictments, was unlawfully appointed to the role.

The rulings from U.S. District Judge Cameron Currie are a significant victory for Comey and James, who both argued their prosecutions are retaliatory and motivated by President Trump's efforts to punish his political foes. The Justice Department is likely to appeal the decisions and ask for them to be halted.
