A suicide bomber killed four people and injured 20 others in a market in Balochistan's Killa Abdullah area late Sunday night, according to Xinhua.

The incident happened around 10:30 p.m. local time, when a suicide attacker detonated an explosive-laden truck near a paramilitary fort. Security personnel intercepted the car as it reached the fort, causing the explosion in the surrounding market.

The injured were transferred to a local hospital for treatment. No group has taken responsibility for the incident. Authorities have cordoned off the area and started an investigation, Xinhua reported.
