The attack is the latest in a wave of deadly sectarian attacks. In January 61 people were killed in a suicide bombing carried out by a Taliban splinter group at a Shiite mosque, the deadliest sectarian incident to hit the country in nearly two years.
At least 23 people were killed in another attack on a Shiite mosque in northwest Pakistan last week, claimed by the Taliban.
