Suicide attacks kill 51

? Pakistan’s turmoil spread from the Afghan frontier to the south, where a suicide bomber struck a convoy carrying Chinese workers – one of three suicide attacks that killed at least 51 people Thursday.

President Gen. Pervez Musharraf called for national unity against extremists enraged by the army’s bloody assault on Islamabad’s Red Mosque.

Suicide attacks, bombings and shootings and the siege of the mosque, which had mounted a Taliban-style anti-vice campaign challenging the government’s authority, have killed about 285 people in Pakistan so far this month, raising concern about the threat posed by Islamic extremists.
