Afghan, U.S. officials sign long-awaited security deal

Officials from Afghanistan and the United States on Tuesday signed a long-delayed security agreement to allow American troops to stay in the country after the end of the year, filling a campaign promise by new President Ashraf Ghani.

National security adviser Hanif Atmar and U.S. Ambassador James Cunningham signed the bilateral security agreement in a televised ceremony at the presidential palace, one day after Ghani was inaugurated.

"As an independent country, based on our national interests, we signed this agreement for stability, goodwill, and prosperity of the our people, stability of the region and the world," Ghani said in a speech after the signing.

Ghani's predecessor, Hamid Karzai, had long refused to agree to the deal, citing his anger over civilian deaths and his belief that the war was not fought in the interests of his country, souring his ties with the United States.

Under the terms of agreement, 12,000 foreign military personnel are expected to stay after 2014, when the combat mission of Afghanistan's U.S.-led NATO force ends.

The force is expected to be made up of 9,800 U.S. troops with the rest from other NATO members. They will train and assist Afghan security forces in the war against the Taliban and its radical Islamist allies.

Ghani was inaugurated on Monday and called on the Taliban to join peace talks. He formed a unity government with election rival Abdullah Abdullah after a prolonged standoff over vote results that ended in a deal to make Ghani president and Abdullah a chief executive in the government with broad powers.

The Taliban, fighting to oust foreign forces and the U.S-backed government, have taken advantage of the paralysis in Kabul to launch attacks in an attempt regain strategic territory in provinces such as Helmand in the south and Kunduz in the north.

The Taliban have denounced the pact with the United States and repeated that on Tuesday, calling it a "sinister" plot by the United States to control Afghanistan and restore its international credibility as a military super power.

"Under the name of the security agreement, today Americans want to prepare themselves for another non-obvious and very dangerous fight," the Taliban said in a statement emailed to the media.

"With their bulk of artifices and deceptions they want to hoodwink the people. They think that the Afghan people do not know about their conspiracies and their sinister goals."
