Shia Muslim demonstrators hold photographs of the victims of a bomb attack during a protest against a suicide bomb attack on a Shia mosque in Peshawar yesterday. At least 23 people were killed in an attack on a Shia mosque in northwest Pakistan on February 13, claimed by the Taliban. Pakistan has suffered a rising tide of sectarian violence in recent years, most of it perpetrated by hardline Sunni groups against minority Shias, who make up around one in five of the population.
