<br/>The Taliban says it was responsible for a weekend attack on the military headquarters in northern Pakistan which left at least 19 people dead. Taliban spokesman Azam Tariq said the attack was carried out by a Punjab faction of the group. Azam Tariq said it was to avenge the recent killing of Pakistani Taliban leader Baitullah Mehsud by a US drone. In a telephone call to news agencies, the spokesman warned of further attacks.
