US President Donald Trump has told President Muhammadu Buhari of Nigeria that the US government will not accept the killings of Christians in Nigeria.

He also condemned the burning of churches in Nigeria, adding that the US government would be working with the Federal of Government of Nigeria to stop the criminality.

Trump said this when Buhari paid him a courtesy visit on Monday just before they had a closed-door meeting.

Many Christians had been killed by  herdsmen in the last few months in the northern parts of Nigeria.
