A series of blasts killed at least one person and wounded dozens as Shi'ite Muslims gathered for a procession in the old part of Bangladesh's capital early yesterday to mark the holy day of Ashura, police said. Islamic State - an ultra-hardline Sunni Muslim group that sees Shi'ites as apostates - claimed responsibility for the attack. But Bangladesh's interior minister told reporters that no militants were involved and the blasts were not linked to an attack that killed 16 people at a Shi'ite procession in neighbouring Pakistan hours earlier. Attacks on the Shi'ite minority have been rare in Sunni-majority Bangladesh, but Sunni militant groups have become more active.
