A bomb targeting a polio protection team in northwestern Pakistan Monday killed at least five police officers, officials said.

"A police truck transporting around 25 policemen for anti-polio campaign duties was targeted by an IED (improvised explosive device)," Anwar ul Haq, a senior government official in Bajaur district, told AFP.

At least 45 people were killed in an explosion at a political rally in the northwestern Pakistani province of Khyber Pakhtunkhwa (formerly the North-West Frontier Province) on Sunday, Reuters reported.

The explosion was caused by a suicide bomber, a police chief said.
