The president said in an evening address from the White House that U.S. intelligence officials tracked al-Zawahri to a home in downtown Kabul where he was hiding out with his family. The president approved the operation last week and it was carried out Sunday.

Malik Faisal Akram, a 44-year-old British citizen, arrived in the U.S. at Kennedy Airport in New York on a tourist visa about two weeks ago, officials said. He spent time in Dallas-area homeless shelters before the attack Saturday in the suburb of Colleyville.

The leader of an Illinois anti-government militia group who authorities say masterminded the 2017 bombing of a Minnesota mosque was sentenced Monday to 53 years in prison on several civil rights and hate crimes for the attack, which left a community terrified.

The document released Saturday, on the 20th anniversary of the attacks, is the first investigative record to be disclosed since President Joe Biden ordered a declassification review of materials that for years have remained out of public view.

The United States completed its withdrawal from Afghanistan late Monday, ending America’s longest war and closing a chapter in military history likely to be remembered for colossal failures, unfulfilled promises and a frantic final exit.

A U.S. drone strike blew up a vehicle carrying “multiple suicide bombers” from Afghanistan’s Islamic State affiliate on Sunday before they could attack the ongoing military evacuation at Kabul’s international airport, American officials said.

Two suicide bombers and gunmen attacked crowds of Afghans flocking to Kabul’s airport Thursday, transforming a scene of desperation into one of horror in the waning days of an airlift for those fleeing the Taliban takeover.

The withdrawal from Bagram Airfield is the clearest indication that the last of the 2,500-3,500 U.S. troops have left Afghanistan or are nearing a departure, months ahead of President Joe Biden’s promise that they would be gone by Sept. 11.

President Joe Biden said Wednesday he will withdraw remaining U.S. troops from the “forever war” in Afghanistan, declaring that the Sept. 11 terror attacks of 20 years ago cannot justify American forces still dying in the nation’s longest war.

People following a violent movement that promotes a second U.S. civil war or the breakdown of modern society have been showing up at recent protests wearing not only tactical gear but an unlikely public and online symbol: the so-called Hawaiian shirt.
