At least 11 people were killed and 20 others injured in an explosion at a police checkpoint in northwestern Pakistan on Saturday, authorities reported. The blast occurred in Dera Ismail Khan, a district situated near the border between Khyber Pakhtunkhwa and Balochistan provinces.

Rescue teams responding to the scene recovered the bodies of eight men, two women, and a child, according to Rescue 1122, the local emergency service. Efforts to retrieve additional victims were ongoing as emergency personnel continued their operations.

Local police officials confirmed that those injured included several police officers, customs personnel, and two civilians. The exact cause of the explosion has not been disclosed, and authorities are likely to conduct further investigations to determine the circumstances surrounding the incident.

No group has claimed responsibility for the attack, underscoring continuing security challenges in the region. Dera Ismail Khan has experienced periodic violence linked to militant activity and cross-border tensions. Officials have heightened security measures in border areas to counter persistent threats.

The explosion adds to a series of violent incidents targeting law enforcement and security forces in Pakistan’s northwestern provinces, where counterterrorism operations are ongoing. Further updates are expected as investigations proceed.
