Investigators are today attempting to identify a suicide bomber who tried to kill Pakistan's interior minister in what officials suspect may have been attack planned by Islamist militants.
At least 26 people were killed and dozens hurt when a man blew himself up yesterday just three metres from the Interior Minister Aftab Ahmed Khan Sherpao in North West Frontier province bordering Afghanistan.
Mr Sherpao, who was meeting people at the end of public meeting in Charsadda, sustained minor leg injuries from shrapnel and pellets.
Investigators found the severed head and torso of the grey-bearded suspect and were trying to establish his identity.
A senior police investigator said the bomber appeared to be in his 30s.
In Washington, a White House spokesman said the attack "shows the terrorists are out there as we saw from this activity in Pakistan but also from the roundup in Saudi Arabia".
Saudi Arabia said on Friday it had thwarted a plot to attack oil facilities and other installations and 172 people had been arrested.
