KARACHI: At least three policemen, including a sub-inspector and two constables, were killed and another wounded early on Wednesday when unidentified attackers opened fire on a police mobile van in Karachi's Bhangoria Goth area, a shanty-town in the limits of the Azizabad police.

The assailants managed to escape from the scene after the attack.

Security and rescue teams reached the spot. Security personnel cordoned off the area as a probe into the incident went underway.

The director-general of Rangers, Major General Bilal Akbar, also visited the attack site.

Sindh's newly-appointed Home Minister Suhail Anwar Siyal also took notice of the incident and sought a report from DIG west Feroz Shah within two days.

Rescue sources said that the policemen were performing their routine night duties when they were attacked. They added that the victims were shifted to a nearby hospital.
