Samuel Aruwan, Commissioner for Internal Security and Home Affairs in the state, made the disclosure in a statement on Saturday night in Kaduna.
Mr Aruwan said security agencies reported the attack on a commercial vehicle around Yakwo village in Chikun Local Government Area.
He said Governor Nasir El-Rufai expressed sadness over the development and prayed for the repose of the souls of those killed by the bandits, while sending condolences to their families.
The commissioner said investigations into the incidents were in progress, as troops continue to intensify patrols in the general areas.
Also in Kaduna, troops of the 271 Nigerian Air Force (NAF) on Saturday foiled an ambush by a group of armed bandits at Ungwan Laya near Birnin Gwari, killing many of them, an official said.
The NAF Director of Public Relations and Information, Ibikunle Daramola, disclosed this in a statement in Abuja.
Mr Daramola said that the troops were able to beat their ways through the ambush, killing several of the bandits who were over 100 in number.
He, however, added that an undisclosed number of gallant personnel of the Nigerian Air force involved in the operation lost their lives, while others sustained injuries and currently receiving treatments.
