Pakistan and Afghanistan vow anti-Taliban co-ordination
[The military chiefs of Afghanistan and Pakistan have agreed to co-ordinate military operations along their border.
The move comes a week after Taliban fighters attacked a school in Peshawar, killing more than 150 people.
Afghan army chief Gen Sher Mohammad Karimi and his counterpart Gen Raheel Sharif met in Islamabad on Tuesday and announced their plans to co-operate.
In the past the two countries have accused each other of allowing cross-border attacks by militants.
The two generals met in the presence of US General John Campbell, who heads Nato coalition forces in Afghanistan.
Gen Karimi and Gen Sharif agreed their subordinates would meet immediately to discuss operations targeting Pakistani Taliban (TTP) bases along the border.
Last week Gen Sharif met Afghanistan's President Ashraf Ghani in Kabul. The two countries agreed to "jointly take effective actions against terrorism and extremism".
Separately, Afghan officials said more than 150 Taliban militants had been killed in military operations in the border province of Kunar.
Taliban militants burst into Army Public School in Peshawar on 16 December, shooting children and staff members.
Security sources now say a total of 152 people were killed. Media reports suggest the attack could have been co-ordinated from Afghanistan.
Following the attack Pakistan's Prime Minister Nawaz Sharif vowed to rid his country of terrorism, and said there would be no distinction between "good and bad" Taliban.
Pakistan has previously been accused by the Afghans and Nato of allowing al-Qaeda and the Afghan Taliban to seek refuge and garner logistical support in Pakistan.
The city of Peshawar is close to the Afghan border, in a region that has seen some of the worst of the violence during years of Taliban insurgency.
