Christian charity Open Doors was informed that armed members of the terrorist organisation - that has pledged allegiance to IS - invaded the Christian community of Kuda near Madagali in Adamawa state, north east Nigeria on Monday.
They then went door to door, killing as many as 25 people.
Funeral arrangements that had begun the following day were promptly halted as bereaved friends and family, sympathisers from neighbouring communities and even security agents fled as the terrorists were spotted again in the community.
Christian leaders in the area told Open Doors: "We are in danger - we have no one to fight for us to end this killing of our people."
Field workers have asked supporters around the world to pray for the Lord's grace to the Church in the Madagali area as they face renewed instability.
A spokesperson from Open Doors told Premier: "Pray for the Holy Spirit to be at work in the lives of all those affected.
"Pray that security will be restored soon."
