An attack on a Sunni Muslim mosque in the southwestern Pakistani city of Quetta has left at least 10 people dead and another 30 wounded, just one day after a suicide bomber killed at least 37 people in the same city.

Friday's attack in the capital of Balochistan province came as most Pakistanis celebrated Eid al-Fitr.
