Pakistan blast targets polio workers

7 October 2013 Last updated at 15:42 BST

Two people, one a police officer, have been killed by a bomb which went off near anti-polio campaigners in Pakistan, say police.

The blast struck a van near a hospital in Budh Bher suburb of the north-western city of Peshawar.

Pakistan is one of only three countries where polio remains endemic, due in part to militant resistance to polio mass vaccination campaigns.
