Sectarian violence in Nigeria's northern Kaduna state, President Muhammadu Buhari has said.

Official presidential Spokesman Garba Shehu tweeted that Mr Buhari found the country's frequent use of violence in such disputes "worrisome".

Without harmony between different groups, "our everyday businesses would be impossible to achieve," the president said.

He called on community leaders to encourage tolerance and stop such discord.
