Polio health centre worker killed
Gunmen have attacked a polio vaccination centre in Pakistan, killing a health worker, police said.
Another worker was also wounded in the attack on the outskirts of Peshawar, police official Raheem Khan said.
The health facility is run by the party of cricketer-turned-politician Imran Khan and authorities are using it to vaccinate children against polio.
No group claimed responsibility for the attack, but militants have killed several polio workers and police protecting them in recent months.
Pakistan is one of only three countries where the polio virus is still endemic.
Militants oppose vaccination against polio and consider such campaigns a cover for spying. They also claim the vaccine is intended to make Muslim boys sterile.
