Gunmen Kill Airforce Officer's Driver, Aide, Others in Kano

It was not clear who was behind the attacks in Kano.

"A car of one of our officers came under attack this morning," Air Commodore Sani Ahmed said.

"The officer's driver and his orderly were travelling out of town, but as they reached an area called Yan-Lemo, two gunmen on a motorcycle opened fire on the car, killing the two personnel."

The officer was not in the car at the time, he said. In a similar incident earlier in the day, two gunmen on a motorcycle shot dead two people outside their house in a nearby neighourhood, said police spokesman Rilwanu Dutse.

A police source said the victims were from the mainly Christian Igbo ethnic group.
