An attack by suspected militants on a prison in southeastern Nigeria was an act of terrorism, President Muhammadu Buhari said.
The attackers targeted a police headquarters and a jail in Imo state late on Monday, the police said in a statement. The raid was carried out by members of the separatist Indigenous People of Biafra and its armed wing, the Eastern Security Network, using “sophisticated weapons” including rocket-propelled grenades and improvised explosive devices, the police said.
