Gunmen kill at least nine women who have been vaccinating children in Kano against polio. In the Hotoro Hayi section, gunmen on motorbikes shoot at least eight women, witnesses tell the Associated Press, while four more people are killed in the Unguwa Uku neighborhood. The final death count is unclear. A campaigner for polio eradication in Nigeria says:
This is certainly a setback for polio eradication in Nigeria, but not a stop. The best we can do is to work harder and see the end of polio … so their loss will not end as a useless sacrifice.
