PESHAWAR, Dec 3 (Reuters) - The Pakistani Taliban on Saturday claimed responsibility for a gun ambush that killed three police officers in northern Pakistan, the second attack claimed by the group just days after it announced an end to a ceasefire with the government. He said three police officers were killed on the spot and the identity of the attackers was unknown. The militant group Tehreek-e-Taliban Pakistan (TTP) claimed responsibility for the attack in a statement. The Afghan Taliban have been facilitating peace talks between local militants and the government since late last year. The Pakistan army has conducted several operations against the militants in their strongholds in lawless districts along Afghan border in recent months.
