Afghan Polio vaccination workers shot dead

Unknown gunmen killed three female polio vaccination health workers in the Afghan city of Jalalabad on Tuesday (March 30), according to officials.

The head of the immunization program at Afghanistan's Health Ministry Ghulam Dastagir Nazari said two volunteers and one supervisor in the polio immunization program were shot in two separate locations in the city.

He added that around the same time, an explosion hit the entrance to the health department of the province of Nangarhar.

The blast rocked the headquarters but left no casualties.

It was not clear who was behind the attacks.

The Taliban spokesman did not immediately respond to request for comment.

A wave of assassinations have hit urban centers since peace talks began between the Taliban and the Afghan government last year in Doha.

Many of them have targeted professional women, as well as government employees and members of the media.
