Kanu said this in a post published on his official Twitter handle on Saturday.
The Biafran leader while making reference to recent killing of soldiers by Boko Haram predicted more killings in the country.
According to him, more Nigerians will be killed if leaders fail to carry out their responsibilities.
The tweet reads: “My broadcast of June 8, 2015 warning that ISIS will attack #Nigeria.
“Recently, the #terrorist group slaughtered Nigerian soldiers.
“The worst is yet to come and more innocent people will lose their lives if community leaders fail to do the needful.”
Meanwhile, Kanu has vowed to release more ‘damning’ proofs to back his claim that a body is impersonating President Muhammadu Buhari in Aso Rock.
Kanu, who said this in a post published yesterday on his official Twitter handle, vowed to ensure the punishment of the Nigerian and Sudanese perpetrators for the alleged fraud.
Recall that the President had during an interactive session with the Nigerian community in Poland, denied the rumour that he was a fake.
