Awalu Mohamed was one of the first to arrive in the mining village of Kuru Karama to discover burned human remains and corpses thrown into communal wells and sewage pits.
“There are so many, many corpses,” says Mr Mohamed, of the Jamatu Nasril Islam aid group.
He described how 62 corpses were pulled from the wells on the first day, but aid workers had no equipment to reach those further down.
“We went to one family and found the entire family there, 20-something of them, including the small, small kids. All of them burned to ashes,” he says.
He covers his eyes.
“As we left, our enemies were busy razing our homes”

He - and other aid workers - realised they were overwhelmed.
Mr Mohamed described how they removed the family’s remains, piece by piece.
They added them to the other corpses inside the wells. These wells are now being sand-filled, to become mass graves.
Around the village, more bodies are being found every day.
Those who tried to run from the gangs were hunted and cut down with machetes and guns around the settlement.
“We could hear the noise. They were singing and chanting, they destroyed everything,” says 20-year-old Zainab Sanusi.
“They burned our house. We are left with nothing now, nothing.”
She fled her home, on the edge of Jos, to join 2,000 other people now eating, washing and sleeping together in cramped classrooms at a local primary school.
‘Homes razed’
Across the region, many thousands are displaced. Everyone has a story to tell.
“Suddenly, a team of security personnel entered our village,” says Mohamed Kabir Mohamed, a miner from Anglo Jos village.
"They told us to evacuate. They were chasing us out, allowing people in to burn our houses.

"Later we realised those police and military men were fake, they were not wearing the proper uniform, the normal military boots.
“When we talked, they opened fire against us. As we left, our enemies were busy razing our homes.”
He and his friends saw very clearly who attacked the village.
‘‘That is the worst part,’’ he says.
‘‘Of those that came, there were known and unknown faces. The worst part is that those who were known, were our friends.’’
The BBC drove through burned out suburbs, villages, and tiny settlements.
The Bukuru Markets area - once a roaring hive of shops - is now a blackened bonfire under a blue sky.
At least 1,000 businesses here were burned.
It was after midnight and people were sleeping when a gang attacked, starting an inferno.
Many people were too disoriented to talk - or too angry to make sense.
The nearby mosque say they received 31 corpses.
The number is hard to believe. It seems too low.
Jos sits on a tense dividing line between Nigeria’s mostly Hausa-speaking Muslim north, and the south where the majority is Christian or practise traditional religions.
The town is predominantly Christian, with Hausa Muslims in the minority.
But people here respect faith. Everyone insists this violence is not about religion.
It is about politics, they say.
Jos has an ugly history of violence at election times.
Local politicians are accused of orchestrating violence to rig elections and intimidate their rivals.
This time, there are accusations the violence is an organised campaign to drive Hausa Muslims out of the state.
The state government denies that. It says it has given 30 million naira ($200,000; £123,000) to help the victims of the violence.
‘Harmony in diversity’
Christian leaders say Muslim mobs also killed Christians during the rioting. But they are refusing to reveal any figures.
“I want the government to intervene on this,” says Chibuzou Aghande, a Christian attending an emotional church service Christian attending an emotional church service in Nassarawa, a few hundreds yards from where the first troubles started.
“Because they know the roots of this thing. Because it is well planned, and they were organised for it. I want the federal government to do something and to bring to book those causing this crisis.”
Worshippers spilled outside the church and hundreds packed the pews inside. Some wept while others murmured responses to a charged sermon.
“Our diversity is meant to create harmony, not disharmony,” Archbishop Ignatius Kaigama told them.
"Your gifts as a Christian should be put to good use so the Muslim can benefit. Your gifts as a Muslim should be put to good use so the Christian can benefit.
