Pakistani police seek clues to suicide bomber's identity

Police examined clothing, shoes and the severed legs of a man today trying to determine the identity of a suicide bomber who killed at least 50 people during a holiday prayer service at a crowded mosque in north-western Pakistan.

Security officers arrested seven students from an Islamic school hours after the blast yesterday, which apparently targeted former Interior Minister Aftab Khan Sherpao, who had been deeply involved in Pakistan’s fight against militants linked to the Taliban and al-Qaida.
