(Telecompaper) MTN risks facing additional fines if it does not meet the year-end deadline to pay the NGN 780 billion imposed already, Nigerian authorities have warned. Nigeria's Communications Minister Adebayo Shittu said that his country will not be cowed or threatened by MTN's announced court challenge of the fine, The Independent reports. Shittu said the decision by the company to approach the Lagos High Court put it at risk of another fine if it failed to meet the deadline. Shittu said while MTN had the right to seek the court's interpretation of the Nigerian Communications Commission's decision, nothing would stop the government from imposing additional fines on the operator at the expiry of the deadline. He noted that MTN had already admitted the infraction when it pleaded for leniency and obtained a reduction in the amount of the fine.
