Second attack was on 15 July 2007, two suicide bombers attacked another Pakistan Army convoy killing 16 soldiers and 5 civilians and wounding another 47 people. And in a separate incident, a fourth suicide bomber attacked a police headquarters killing 28 police officers and recruits and wounding 35 people. The assault on the Red Mosque prompted Islamic militants along the border with Afghanistan to scrap the controversial Waziristan Accord with Musharraf. Under pressured, Musharraf moved the army in large concentration of troops into Waziristan and engaged in fierce clashes with militants in which at least 100 militants were killed, including wanted terrorist and former Guantanamo Bay detainee, Abdullah Mehsud.
