The group also threatened to shut down oil exploration in the Nigeria/Cameroon maritime borders.

The Federal government has been issued a 14-day ultimatum by the leader of Biafra Nations League, BnL, Princewill Chimezie Richard to release the embattled leader of the Indigenous People of Biafra, Mazi Nnamdi Kanu.

The group also threatened to shut down oil exploration in the Nigeria/Cameroon maritime borders.

It has also gave same ultimatum to the Nigerian government to withdrawal military troops from the South-East region.

At a press briefing in Calabar, they also called on Cameroon authorities “to desist from forcing and collecting proliferated taxes from Nigerians living in the Bakassi Peninsula.”

Richard said, “We want to use this medium to reiterate our decisions to shut down maritime borders if our demands are not met within 14 days, effective from 8 May, 2022.’

He claimed that BnL was enjoying support from other groups.

“We are capable of doing anything. We cannot disclose extent of our capacity.

“You should know that we command massive loyalists and followers even amongst the natives. It will be disastrous if our demands are not met.”

He called on President Muhammadu Buhari to release Kanu before he hands over on 29 May, 2023, and stop being recalcitrant by not obeying court orders.

“We are disappointed and have lost confidence in Buhari’s government”.

“I can’t say I have confidence in Bola Ahmed Tinubu who would be replacing Buhari. I don’t even know him.

“Even if Kanu is released, it will not stop our agitation for Biafra sovereignty. We are demanding for safety and freedom from Nigeria. We have never believed in Nigeria.

“BnL is not alone in this struggle. There will be no negotiation about Biafra.”

The group said Nigerian authorities should not force them to take laws into their hands.
