Taliban militants today kept up an unrelenting wave of terror campaign in Pakistan with a suicide car bomber striking a police station in Peshawar killing 13 people and wounding 16 others. Targeting the city for the second day in running, the bomber rammed his explosive laden car into the police station creating an impact which also severely damaged a nearby mosque. In 12 days of wanton violence, the terrorists have carried out numerous suicide bombing, blasts and attacks, including the storming of Army Headquarters in Rawalpindi and three synchronised attacks on law enforcement establishments in Lahore yesterday leaving a trail of 174 deaths. Meanwhile, with terror toll mounting, Pakistan law enforcement agencies began swoops countrywide in which over 80 people suspected to be involved in the recent spate of deadly strikes have been arrested. In a related development the security forces continued their pounding of Waziristan using fighter jets and artillery guns to soften the Taliban defences in the area. An emergency was declared in all hospitals in Peshawar, where authorities have been on high alert for the past few weeks in the wake of a wave of deadly attacks.
