A crowd gather at the site of the blast.

A bombing at a crowded bazaar in southwestern Pakistan on Sunday killed at least five people and wounded 16, authorities said amid a surge in violence in this South Asian nation.

No one immediately claimed responsibility for the attack in Barkhan, about 600 kilometers (360 miles) northeast of Quetta, the provincial capital.

Sajjad Afzal, the local police chief, said the bomb was apparently rigged to a motorcycle and was detonated by remote control. Apart from inflicting casualties, the bombing also left several shops at the market badly damaged. Rescuers took the wounded to hospital, Afzal said.

Abdul Qudoos Bizenjo, the chief minister of Baluchistan, condemned the bombing, describing it as a terrorist attack.

"Terrorists are trying to create uncertainty through such attacks to achieve their nefarious goals, but we will not allow these anti-state elements to succeed, " he said without specifically blaming anyone.
