ISLAMABAD, Pakistan — Pakistan’s army chief, Gen. Ashfaq Parvez Kayani, confirmed Sunday that he would retire next month, laying to rest media speculation that he would extend his term or take a powerful new position in the military.

General Kayani, 61, who has already served two three-year terms as army chief, said in a statement released through the military press office that he would step down on Nov. 29.

“It is time for others to carry forward the mission of making Pakistan a truly democratic, prosperous and peaceful country,” he said.

The announcement was significant because it paves the way for the appointment of a new army chief — always a delicate matter in a country that has suffered four military coups — at a time when Pakistan’s military is playing a central role in dealings with Taliban insurgents in both Pakistan and Afghanistan.
