Islamabad: Eleven people including six soldiers were killed when a suicide bomber smashed his explosive-packed vehicle into a military convoy in a restive tribal district in Pakistan's North West Frontier Province (NWFP), security sources said.
It was unclear whether the bombing had a connection with the Red Mosque battles between security forces and militant students in Islamabad.
Chief Pakistani military spokesman Major General Waheed Arshad said he had so far received reports that four soldiers were killed and six injured, two critically, in an attack in Mir Ali.
Also in NWFP, in the Swat region, an explosion from a planted improvised explosive device injured five police, including the district police officer, sources said.
Earlier a grenade was lobbed at a police station in Swat, killing a constable, the sources said.
Swat is the base of a banned extremist group, Tehreek Niafaz-e-Sharia- Mohammadi. Officials say trained militants of the group were also present inside the Red Mosque.
The group has been outlawed in 2002.
