Sectarian violence spreads in Pakistan

Sectarian violence spread in Pakistan on Monday after clashes between minority Shi'ite and majority Sunni Muslims near the capital Islamabad prompted the government to impose a curfew and block mobile phone services over the weekend.

Clashes confined to areas in and around the capital at the weekend spilled over on Monday into two towns in the volatile northwest. (Reuters)
