There is panic in Abuja after an unverified video on social media showed a Camroonian tank on a bridge at a border post identified as Mfun Bridge.
A Nigerian official was seen and heard in the video expressing reservations on the breach of international laws. He claimed shots were fired into Nigeria.
Efforts were being made at press time to verify the authenticity of the video and when it was shot. An accompanying caption from a source put the date at Wednesday, 14th March, 2018.
