Gunmen Kill Polio Worker in Pakistan

Last year, World Health Organization officials suspended a polio vaccination campaign in Pakistan after a series of attacks on polio workers left at least eight people dead.

Pakistan, Afghanistan and Nigeria are the only three countries where polio remains endemic.



Meanwhile, officials say two people were killed and about a dozen injured in a blast in Peshawar.

Also, officials say gunmen shot dead a lawyer and his two children in Karachi. Authorities say the attackers opened fire on high court lawyer Kosar Saqlain as he was taking his children to school.
