Nigeria's illegal oil refineries: Victims of blast buried in mass graves

The remains of more than 100 victims killed in a weekend explosion of an illegal oil refinery were buried on Tuesday evening in three mass graves, officials said.

President Muhammadu Buhari described the incident in Imo state, southern Nigeria, as a "catastrophe and a national disaster".

No family members were present at the burial as many of the bodies were burnt beyond recognition.

Ezekwe Bigwig, a local community youth leader, said: "The shock is still within us."
