Explosion rocks Shia Muslim rally in Pakistan

At least 22 people have died in a bomb at a Shia Muslim rally in the south-western Pakistani city of Quetta.

Many others were injured in the explosion, which happened in the Meezan Chowk area. Reports suggest the blast was followed by firing.

Rallies are held across Pakistan every year on the last Friday of the Muslim fasting month of Ramadan to support Palestinian demands for a separate homeland.
