NEW YORK — New York City Mayor Michael Bloomberg said Americans have kept their promise after Sept. 11 to capture or kill Osama bin Laden.

President Barack Obama announced Sunday night bin Laden was killed in an operation led by the United States.

Bloomberg said the killing of the terrorist leader doesn’t lessen the suffering Americans experienced at his hands the day the World Trade Center was destroyed but is a “critically important victory” for the nation. He says it’s a tribute to the men and women in the armed forces who’ve fought so hard.

The 10th anniversary of the Sept. 11, 2001, attacks is just months away.

Bloomberg said in a statement he hopes news of bin Laden’s demise will “bring some closure and comfort to all those who lost loved ones” that day.
