The Kaduna State Government has reinstated the 24-hour curfew it initially relaxed in the state.
A statement by Samuel Aruwan, Senior Special Assistant to the Governor (Media and Publicity) on Friday, noted that the curfew will affect Kaduna metropolis and environs, Kasuwan Magani, Kajuru, Kateri and Kachi.
The curfew took effect from 11am on Friday.
The government also confirmed the murder of a traditional ruler in Kaduna State, the Agom Adara, His Royal Highness Maiwada Galadima.
According to the statement, the curfew is a "necessary step to help maintain peace".
The statement continued: "We mourn the death of HRH Agom Adara, who we lost in the early hours of today to the criminals who abducted him last week.
"The Kaduna State Government calls for calm in all pur communities. The criminal elements who perpetrated this crime should not be allowed to divide us.
"This is a struggle between good, decent, law-abiding people trying to uphold the peace and criminals who want to divide and destroy. It is not a struggle between religious or ethnic groups. Let no criminal find succour in faith or tribe.
"Let us unite against every criminal activity. Let us stand together as human beings who have a right to live in peace."
