A bomb has killed one person in south-western Pakistan, in an attack near to a paramilitary vehicle.
There have been 15 people injured in the blast, in Khuzdar, 250km south of Quetta, capital of Balochistan province.
There were reports that the bomb was planted in a parked bicycle and detonated by remote control.
Elsewhere, a suspected Islamic militant was killed and a policeman injured in a shootout in Lahore.
It followed a police raid in the city's Kot Lakhpat neighbourhood, following a tip-off.
The dead militant has been identified by the police as Mohabbat Khan, and is said to be of Afghan origin.
Quetta bomb
There have been no claims of responsibility for the bomb in Balochistan - the latest in a string of attacks.
The BBC's Azizullah Khan in Quetta says the bomb exploded near a paramilitary vehicle.
But a spokesman for the paramilitary forces denied that any of his men had been injured in the explosion - and claimed they had not been the target of the bomb.
Two of the injured are reported to be in a critical condition - and shops, buses and vehicles were damaged by the impact of the blast.
Officials say the bomb was fixed to a bicycle left in a market and detonated remotely. But a report from the Reuters news agency claimed the explosive device had been thrown at a vehicle.
There has been a series of bomb attacks in the area, including a truck bomb which exploded outside a police station in Quetta on Wednesday, but caused no injuries.
Earlier this month, four people were hurt in a car bomb blast in Quetta, near to the office of the province's chief minister, Jam Mohammad Yousuf.
In August, five security personnel and a civilian were killed in an attack on a military vehicle in Khuzdar.
In previous attacks, there have been suspicions about "nationalist" groups opposed to the government. The area has also seen sectarian attacks between religious groups.
An attack on the chief minister's motorcade in the summer had been claimed by the Baloch Liberation Army.
