Deadly double bombing in Pakistan

Two bombs in the Pakistani city of Karachi have killed at least 22 people and injured more than 50.

In the first blast, a motorbike laden with explosives hit a bus carrying Shia Muslims to a religious procession and exploded, killing 12 people.

An hour later, another bomb exploded outside the entrance to the emergency ward of the hospital where the victims of the first attack were being treated.
