Gunmen on a motocycle on Wednesday shot dead two officers of the Federal Road Safety Commission in Kano, Kano State.
The killers were suspected to be members of the violent Islamic sect, Boko Haram.
One other FRSC official sustained bullet wounds.
The killing occurred at about 1pm around Madobi Road, near Sani Abacha Youth Centre, in Panshekera, a suburb of Kano metropolis.
The incident came barely 24 hours after two policemen were shot dead by suspected gunmen in the city.
A policeman close to the scene of the incident, who preferred anonymity, told our correspondent that, “A Federal Road Safety Commission patrol vehicle was attacked by gunmen on a motorbike, killing two officers and wounding one.”
Sector Commander of the FRSC, Kano State Command, Zaaki Alkali confirmed the incident to journalists.
He said his men were four in the vehicle when the attackers opened fire on them.
“Two officers died instantly, while one sustained bullet wounds, but the fourth person survived the attack unhurt. It is a very sad incident”, Alkali explained.
