The site is attracting members of the congregation who want to revisit the scene after lucky escapes as well as curious people from surrounding neighbourhoods who come armed with mobile phone cameras.
The authorities suspect the militant Islamist sect, Boko Haram, was behind Sunday’s attack.
But the bombs are not the only cause of fear in northern Nigeria. In some towns and cities the military response is also causing people to suffer.
“After Boko Haram attacked a mobile military patrol, soldiers came to the place and started firing on people, innocent people,” a trader who recently fled the town of Potiskum told the BBC.
“When I went to the hospital the next morning I saw 30 bodies. I saw them with my naked eyes. I counted them.”
Residents of towns in north-east Nigeria say that civilians are most at risk when soldiers are killed by suspected Boko Haram militants.
There were reports last month that a tipper truck had dumped dozens of bodies at the hospital in Maiduguri – a stronghold of Boko Haram – after a military crackdown in the city. The army denied the allegations.
In recent weeks people have been fleeing the worst affected areas – some temporarily – and they bring with them accounts of atrocities.
