At least seven people have died in a bomb blast in south-western Pakistan, and six are injured, police in the region say.
The explosion took place in the town of Dera Bugti in Balochistan province.
Some reports say the explosion was in a market, while others say the bomb was on a bus at a bus station.
Militants in Balochistan have been fighting for greater autonomy for the mineral-rich province for the last five years.
The Balochistan explosion was not thought to be directly related to Thursday's bomb blasts in Karachi, which killed 130 people.
The Karachi blasts were an unsuccessful attempt on the life of former Prime Minister Benazir Bhutto, as she returned to Pakistan after eight years' self-imposed exile.
