Militants driving a smashed SUV and motorbikes threw an Improvised Explosive Device (IED) at the convoy of the The Emir of Kano, Ado Bayero, and then shot at his official vehicle, killing his driver and three of his guards, according to a military source.
The attack took place near the Hockey Field on Zoo Road by Total Gasoline station while the Emir was returning from the launching of an Islamic school at Mussalaci Murtala.
The Emir was unhurt in the attack and has since been moved to an undisclosed location.
Some residents in the area said Nigerian troops of the Joint Task Force later took over the scene of the attack while firing shots.
JTF spokesperson in Kano, Captain Ikedichi Iweha said he was still trying to get the full details of the attack, asking to speak with Saharareporters as soon as official incident report becomes available.
