The President Muhammadu Buhari-led Presidency was urged to free Nnamdi Kanu by the Indigenous People of Biafra (IPOB) on Saturday.
The Buhari-led Presidency should free Kanu, according to IPOB's spokesman Emma Powerful, to avert doomsday.
Kanu's resolve won't be broken, according to those who are tormenting him with the use of unfair tactics and coercion, Powerful stated.
"The global family and movement of the Indigenous People of Biafra (IPOB) under the command of our indomitable leaders and Mazi Nnamdi Kanu once again publicly raise alarm on the deteriorating health condition of our leader in the DSS solitary confinement," according to a statement from Powerful.
"We, therefore, again call for his unconditional release in accordance with the court's ruling so that he can receive appropriate medical attention and treatment.
"Neither Mazi Nnamdi Kanu's resolution nor IPOB's resolve to pursue Biafra independence will be broken by those who are torturing him using the tools of injustice and pressure, not now, not tomorrow, and not forever.
“The Nigerian government and its supporters should understand that Mazi Nnamdi Kanu is a living legend that Biafrans will not trade with anything in this world.
"In order to prevent doomsday, Mazi Nnamdi Kanu must be unconditionally released as mandated by the courts. A stitch in time saves nine.”
