Four policemen shot dead in Karachi’s Orangi Town

At least four police officials were killed and three injured in two separate attacks in the city’s Orangi Town, DawnNews reported.

Unknown gunmen riding a motorcycle opened fire on a police vehicle, which was deployed for the security of polio vaccination officials, DawnNews reported. All four policemen on board the vehicle succumbed to their wounds on the way to the hospital.

Immediately after attacking the vehicle, the gunmen sped away and opened fire on three other policemen, who were also on duty in the area, eye witnesses said.

There are no reports of injuries or deaths of polio workers so far.

The campaign to eliminate polio in Pakistan has been fraught with risk, with militants attacking health teams they accused of being spies.

A polio worker was shot and wounded in February and in January a suicide bomber killed 15 people outside a polio eradication centre in Quetta.

Pakistan and Afghanistan are the only countries in the world which have been transferring the polio virus to each other.
