A soldier and policeman were among the people killed by suspected bandits along Kaduna-Abuja road on Sunday.
The suspects also robbed and abducted many people near Gidan Busa village on the highway.

Witnesses said the incident took place around 7pm and lasted for at least an hour.
He said the attackers numbering 10, had sophisticated weapons. Policemen at a nearby checkpoint were alerted but could not confront the suspects.
Many people traveling to and from Kaduna have long abandoned the road for train services.
A special police security task force was deployed to strategic points on the highway, but the bandits have continued to operate.
