The Biafran activists staged the protest just a few metres from Buckingham Palace, London where Nigeria's President Muhammadu Buhari met with the Queen of England and other Heads of state at the Commonwealth head of governments.
The protesters were seen carrying placards with different inscriptions, demanding the whereabouts of Nnamdi Kanu, the missing leader of the Indigenous people of Biafra as well as calling for a referendum.
