According to the report,
Eleven people have reportedly been killed in southeastern Nigeria during celebrations to mark the impending inauguration of US President-elect Donald Trump.
The Indigenous People of Biafra (IPOB) organised an event, dubbed a solidarity rally, in the city of Port Harcourt. IPOB advocates for the formation of an independent state of Biafra in the country's southeast.
Unconfirmed reports from the Nigerian Naij.com news website say that 11 people were killed during the event as police and the army "shot unarmed Biafrans".
IPOB's English news website said "over a dozen" fatalities had been recorded at the rally and more than 100 arrests.
A photographs posted on an IPOB Twitter account showed a bloodied still body lying on a stretcher.
Several social media sources also published photos of participants bearing placards in support of the president-elect one of which read: "Trump you are our victory congratulations".
Other photos showed crowds waving the US, Israeli and Biafran flags.
IPOB leader Nnamdi Kanu has been in prison since October 2015 when he was arrested charged with "criminal conspiracy, intimidation and membership of an illegal organisation". The case is yet to be resolved.
The separatist group has renamed its push for secession "Biafrexit" after the UK's Brexit vote to leave the European Union. Prince Emmanuel Kanu, Nnamdi's brother, has said Trump won their backing as he "supports the right to self-determination" advocated by IPOB.
