People gather at the scene of a Bomb Atack attack in Pakistan.

At least eight people including seven cops were injured when a bomb went off near a police vehicle in Pakistan's northwest Peshawar city on Thursday, local Urdu media reported.

Express TV reported that the personnel from the Rapid Response Force (RRF) were on routine patrolling on their van when it was hit by the bomb at Warsak Road area of Peshawar, the capital city of the country's northwest Khyber Pakhtunkhwa province.

Police said that some unknown militants blew up the roadside planted bomb with a remote controlled device and fled the scene.

The injured people were shifted to Lady Reading Hospital where one of them is said to be in critical condition.

Outlawed organization Tehreek-i-Taliban Pakistan claimed responsibility for the attack in a telephone call to local media, the report added.

Police cordoned off the area for investigations.

Thursday's attack is the continuation of the latest string of attacks on police in the country.

A total of 11 policemen have been killed and three others injured in separate attacks in the country's Sindh, Balochistan and Khyber Pakhtunkhwa provinces in the last one week.

Earlier on Wednesday night, two policemen were killed in firing by unknown gunmen in Karachi, the provincial capital of Sindh.
