Armed men attacked a police armoured vehicle that was on security duty at a polling station at Kot-Azam in Tank area in Pakistan on Monday.

The attack triggered an exchange of fire that left one attacker dead.

The polling process had to be stopped for some time due to the ambush, though it resumed following a search and clearance operation by police, reported Dawn News.

The police vehicle was on security duty for re-polling on six polling stations at the National Assembly (NA-43) constituency of Tank-cum-Dera Ismail Khan, the newspaper reported.

Amid the deteriorating law and order situation, voting did not take place on February 8 at six polling stations including one at Kot-Azam in Tank and five in Kalachi tehsil of D.I. Khan.

A total of 5,438 registered voters were eligible to cast votes at these six polling stations. Officials said re-polling was held ‘peacefully’ amid tight security in rest of the polling stations, after the attack, reported Dawn News.
