Kidnappers have killed two Nigerian policemen and abducted two Americans and two Canadians in Kaduna state.
The foreigners were kidnapped on Kwoi-Jere Road in Kagarko Local Government Area on their way to Abuja from Kafanchan and Kaura.
They were ambushed around 7pm on Tuesday.
Kidnapping is rife in the Kaduna axis of the country and despite efforts by the police in flushing out suspects, it continues.
