KARACHI, Pakistan (AA) – At least one policeman was killed and six others injured in a suicide blast in Pakistan's capital Islamabad on Friday, police said.

The Islamabad police tweeted they were conducting snap-checking when they signaled a suspicious vehicle to stop.

When the policemen reached the vehicle, the suspected bombers blew the explosive-laden vehicle up, Interior Minister Rana Sanaullah told reporters.

Both suspected bombers, including a woman, he added, were also killed in the bombing, which was aimed at a "high-value" target in Islamabad.

Dr. Khalid Mehsud, the director of the Pakistan Institute of Medical Sciences, told reporters that two bodies and 10 injured were brought to the hospital.

The police said the explosion was caused by some explosive material placed inside the vehicle.

Islamabad has been under security alert for the last several days, following the taking over of a counter-terrorism facility in the northwestern Bannu district this week.

Security forces took control of the Parliament House earlier this week amid a security threat.

Footage aired on Geo News showed the taxi lying overturned in the middle of a road with plumes of fire wafting upwards.

There was no immediate claim of responsibility for the incident.
