Mobile phone carrier, MTN Group Limited, Monday said attackers of telecommunications' towers in the North-east geo-political zone of the country destroyed its fibre-optic lines, which ran through the region.
In a statement, the South African-based company, it said the multiple cuts on the line had disrupted "the lives of millions" in the region.
The Associated Press (AP) reported that the company offered no estimate on how much damage was done nor the cost of repairs.
Gunmen suspected to be members of the Boko Haram had on September 5, attacked about 30 mobile phone towers across the region, disrupting service for all telecommunication companies.
Though Boko Haram later claimed responsibility for the attacks, the sect in justifying its actions alleged that mobile phone companies had helped the government to arrests its members.
