The Taliban had mocking words for the U.S. as the war in Afghanistan entered its 12th year on Sunday, claiming U.S. and NATO forces are "fleeing" with "humiliation and disgrace."

The last international combat forces are scheduled to leave Afghanistan by the end of 2014 after the U.S.-led invasion Oct. 7, 2001 following the 9/11 terror attacks.

"With the help of Allah, the valiant Afghans under the Jihadi leadership of Islamic Emirate defeated the military might and numerous strategies of America and NATO alliance," the Taliban said in a statement Sunday, according to AFP.

"And now after eleven years of unceasing terror, tyranny, crimes and savagery, they are fleeing Afghanistan with such humiliation and disgrace that they are struggling to provide an explanation," it said.

More than 3,100 NATO troops have been killed since the war began, according to the independent website iCasualties.org. Of those troop fatalities, more than 2,000 have been American.
