Kaduna State governor, Nasir El-Rufai has said President Muhammadu Buhari is sad over the killings in the Southern area of the state.
President Muhammadu Buhari has not been seen since leaving Africa's most populous country, which is battling an economic crisis, terrorism and a regional starvation, for medical treatment at the beginning of May.
President Buhari had not been seen in public since leaving Nigeria on May 7th, 2017 for treatment in the United Kingdom.
He said the president has lost weight.
But, on Sunday a delegation of governors elected on the platform of the All Progressives Congress met with Buhari in London.
The health of Nigeria's president has been a sensitive issue since the death in office of president Umaru Musa Yar'Adua in 2010 after months of treatment overseas.

He dismissed the insinuation that Ekiti State Governor Ayo Fayose, a fierce critic of Buhari's who has also claimed that the president was on life support, was deliberately sidelined from the trip.
On when the president would return, Adesina stated: "That already is in public domain".
"His date of return will be decided by that medical team".
Buhari, 74, was "very cheerful" and will return "as soon as the doctors give him the green light", Femi Adesina, a spokesman, said in an emailed statement.
"More meetings are coming; there will be broader ones".
The actor described the emergency meeting held in London on Sunday as a house warming of new seat of government in Abuja house, London.
Adesina said the two ministers who have been confirmed by the senate would soon be sworn in.
He also said the presidency is not anxious about the legal actions seeking to compel the Federal Executive Council to declare Buhari incapacitated.
