At least seven people have been killed following an explosion that struck a security checkpoint manned by Cameroon Gendarmes near residential quarters used by staff of an oil company in the Bakassi Peninsula.
Eyewitnesses report that the attackers arrived in a small fishing boat, moved close to the checkpoint and threw explosive devices before jumping into the water.
Two speedboats later appeared and reportedly picked up the attackers.
Authorities have not yet identified the group responsible, but there are strong indications that the group behind the attack could be affiliated to the Indigenous People Of Biafra (IPOB).
Meanwhile, violence has continued to rock the Bakassi region, especially in clashes involving separatist fighters and security forces from both Nigeria and Cameroon, raising concerns about worsening instability in the area.
This latest incident also comes days after the Operational Coordinator of the Biafra Nations League (BnL) issued a statement calling on the Nigerian government to release Nnamdi Kanu on the 20th, a key date in his court proceedings.
Observers warn that tensions may rise further if the situation is not carefully managed.
