U.S. Defense Secretary Ash Carter says the country's enemies - wherever they are - will ''come to feel the righteous fist of American might.'' Rough Cut (no reporter narration).
ROUGH CUT (NO REPORTER NARRATION) U.S. President Barack Obama and U.S. Defense Secretary Ash Carter commemorated the 15th anniversary of the Sept. 11, 2001 attacks on Sunday with a ceremony at the Pentagon, where 184 people were killed when hijackers flew a plane into the Department of Defense building. During his remarks, Carter paid respect to the men and women in uniform who responded to the attacks with endless resolve. "Our enemies cannot hide, they cannot escape, they cannot endure," Carter said. "Wherever they are, they will surely, no matter how long it takes, come to feel the righteous fist of American might." Meanwhile, in New York, the names of the 2,983 victims were read slowly by relatives as classical music played during a ceremony at the 9/11 Memorial plaza in lower Manhattan with pauses for six moments of silence. Four of those mark the exact times four hijacked planes were crashed into the World Trade Center, the Pentagon near Washington D.C., and a Pennsylvania field. The last two record when the North and South towers of the Trade Center crumpled. The ceremony was held by two reflecting pools with waterfalls that now stand in the towers' former footprints, and watched over by an honor guard of police and firefighters. More than 340 firefighters and 60 police were killed on the that sunny Tuesday morning in 2001, in the worst attack on U.S. soil since Pearl Harbor was bombed in 1941. Many of the first responders died while running up stairs in the hope of reaching victims trapped on the towers' higher floors. Houses of worship throughout the city tolled their bells at 8:46 a.m. EDT (1246 GMT), the time American Airlines Flight 11 slammed into the North Tower. A second pause came at 9:03 a.m. (1303 GMT), when United Airlines Flight 175 struck the South Tower. American Airlines Flight 77 hit the Pentagon at 9:37 a.m. (1337 GMT), then the South Tower collapsed at 9:59 a.m. (1359 GMT). At 10:03 a.m. (1403 GMT) United Flight 93 crashed near Shanksville, Pennsylvania, and the final moment of silence will be observed at 10:28 a.m. (1428 GMT) when the North Tower fell. As evening falls across the city on Sunday, spotlights will project two giant beams of light into the night sky to represent the fallen twin towers, fading away at dawn. Nineteen hijackers died in the attack, later claimed by Osama bin Laden and al Qaeda, which led directly to the U.S. war in Afghanistan and indirectly to the invasion of Iraq.
