Update at 12:28 a.m. ET, May 2. Bin Laden "Did Resist":
According to senior administration officials briefing reporters, bin Laden did "resist the assault force" during the firefight that led to his death.
They've also told reporters that no other nation was told in advance of the raid.
Update at 12:25 a.m. ET, May 2: "Surgical" Operation:
Senior administration officials are briefing reporters now on some of the operation's details. They say that along with bin Laden, three adult males and one women were killed. The woman, they say, was being used as a shield by one of the men. The operation, they say, was a "surgical" raid carried out by a small team that flew to the site on helicopters. One helicopter, they say, had problems and was destroyed at the site by the U.S. personnel — who then flew out aboard the other helicopter.
