The death toll in a suicide car bombing at an army check post in the restive North Waziristan tribal region of Pakistan has risen to 17, a military spokesman said on Sunday.
The suicide bomber rammed an explosives-laden vehicle into Esha check post near Miranshah, the main town of North Waziristan Agency, on Saturday night.
Six security personnel were killed instantly and 11 more died later.
Over a dozen security personnel were injured, officials said earlier.
Troops cordoned off the area after the attack and launched a search operation. Authorities imposed a curfew in the region.
No group claimed responsibility for the suicide attack.
North Waziristan is considered a safe haven for Taliban and Al Qaeda elements.
