Nigerian security forces opened fire on protesters who were rallying over the deaths of 37 miners in detention, according to Al Jazeera.

The protests followed the deaths of the miners, who died in detention this week. The source says the demonstrators were angry about the fatalities and gathered to demand accountability.

Al Jazeera reports that a paramilitary agency had raided a suspected illegal mine before the miners died. The supplied report does not identify the agency, describe the circumstances of the deaths in further detail or say how long the miners were held.

The account also does not provide information on possible casualties among the protesters, the location of the demonstration or whether any arrests were made. It likewise does not state what prompted security forces to open fire or whether officials have offered an explanation.

The deaths and the response have brought protesters into confrontation with Nigerian security forces. Further details, including the identities of the miners and the authorities involved in the detention, were not included in the supplied material.
