WASHINGTON - The U.S. Navy SEALs on the hunt for Usama bin Laden killed the Al Qaeda leader within 2 minutes of entering his home in Abbottabad, a new book reveals. Chuck Pfarrer, a former SEAL Team Six assault-element commander, says it only took the SEALs 90 to 120 seconds from landing to firing the fatal shot to take out bin Laden, according to his new book, Seal Target Geronimo (Osama's code name), the New York Post reports. Pfarrer's account, which he says came from several men involved in the May attack on the al-Qaeda leader, contradicts the official government account that says Osama bin Laden was killed in a 45-minute firefight. "Bin Laden was dead within 90 seconds of the beginning of the raid, not after an extended firefight," Pfrarrer said in a statement. "Four suppressed rounds were fired." Pfarrers book reveals that the Seals nickname for bin Laden and his deputy, Ayman al-Zawahiri, were Bert and Ernie, The Courier Mail reports. When they were first told they were going to Pakistan to pick up a high-value person who was holed up in a high-walled compound, they asked, So is this Bert or Ernie? According to a published extract, two Seals kicked in bin Ladens bedroom door. Bin Laden then popped out and then slammed the door shut. The room, the Navy Seals recalled, smelt like old clothing, like a guest bedroom in a grandmothers house. Inside was the Al Qaeda leader and his youngest wife, Amal, who was screaming as he pushed her in front of him. No, no, dont do this she shouted as her husband reached across the bed for his AK-47 assault rifle, the extract read. The SEALs reacted instantly, firing in the same second. One round thudded into the mattress. The other aimed at Bin Ladens head, grazed Amal in the calf. As Bin Ladens hand reached for the gun, the Seals fired again, killing the Al Qaeda leader. Pfarrers book, according to the Post, also reveals that the SEALs were angry with President Barack Obama for announcing bin Ladens death on TV just hours after they completed the mission on May 1.
