Funerals have taken place in southern Pakistan for the victims of a suicide attack on a Shia mosque during Friday prayers which police say killed at least 60 people.
Dozens were also wounded in the attack in Sindh province’s Shikarpur district, making it one of the worst sectarian attacks in Pakistan in recent years.
Sunni militants linked to the Taliban said they carried out the attack.
An official day of mourning has been declared across Sindh.
Some Shia groups burned tyres and blocked roads during protest rallies in Shikarpur town – where the attack took place.
Protests also took place in other cities.
Shias are demanding the arrest of those who orchestrated the attack and better protection for their places of worship.
Police say that the bomber detonated explosives strapped to his body in the centre of the mosque. Four children were reported to be among the dead.
