Pakistani officials say a bomb blast has killed at least five people in the southwestern city of Quetta.
The device exploded Monday on a busy street during the morning rush hour.
Police say the bomb was attached to a bicycle parked outside a shop. The explosion badly damaged the shop and a nearby hotel. At least 17 people were wounded.
No one has claimed responsibility for the attack. Pakistani officials are blaming renegade tribesman from Baluchistan province, of which Quetta is the capital.
A rebel group called the Baluchistan Liberation Army has carried out a wave of small-scale bombings in the province in recent years.
The rebels say they are fighting for a greater share of the Baluchistan's rich oil and gas reserves.Some information for this report was provided by AFP, AP and Reuters.
