A coroner's inquest into a 2010 fiery car crash in Nigeria that killed at least 18 people has blamed police and the nation's top corporation for the deaths, highlighting the challenges facing the nation.

Coroner T.A. Elias issued a ruling Wednesday in the investigation into the crash in Lagos, Nigeria's largest city. Elias blamed police for mounting an illegal checkpoint on a busy expressway. They also blamed a semi-truck with bad brakes carrying sugar for the Dangote Group, owned by billionaire Aliko Dangote.

Both police and major companies remain largely untouchable in Nigeria, an oil-rich nation strangled by entrenched corruption. Lawyers who asked for the inquest said the ruling shows the country's legal system, though flawed, still has power.
