Kanu and others would appear in court on December 1.
The Leader of MASSOB, Uchenna Madu, in a statement on Monday, called on Igbo to intensify the efforts towards the release of Kanu and other detained pro-Biafran agitators.
Madu said all MASSOB members in Imo State would converge on the group’s headquarters in Okwe, Onuimo Local Government Area of the state for the prayer session.
The MASSOB leader also stated that other pro-Biafran groups, including IPOB remained the pride of the Ndigbo.
He noted that the emergence of groups such as Oodua Peoples Congress, Niger Delta Avengers and Boko Haram had shown that the country was not united.
