The gunmen riding on tricycles opened fire on health workers at Hotoro Haye and Shargalle Health Centre in the Kano metropolis as the health workers prepare their polio vaccination cocktails for the day.
Two women were felled by the militants bullets at Unguwa Uku while seven others died from the lethal attack on Shargalle Health Centre in attacks that took place thirty minutes apart.
Police spokesperson Musa Majia confirmed the attacks to journalists stating that the gunmen had fled the scene of the attack before security agents could reach the area.
Several Islamic clerics are opposed to polio vaccination claiming that it was a western scheme to limit Muslim population in Nigeria.
