Gunmen kill 9 in attacks on Nigeria polio clinics

Gunmen attacked two clinics where polio vaccinators had gathered in the northern Nigerian city of Kano on Friday, killing nine people before fleeing, police and residents said.

"Nine people were killed in two separate attacks by gunmen on (motorised) tricycles when they attacked two dispensaries where polio immunisation workers were preparing to go out for polio campaigns," police spokesman Magaji Majia told AFP.
