The Defence Headquarters said that over 13,000 terrorists and their families have so far surrendered to troops in the North East.
The Acting Director, Defence Media Operations, Bernard Onyeuko, disclosed this while giving update on the military operations across the country in Abuja.
According to Mr Onyeuko, the surrendered terrorists comprise 3,243 males, 3,868 females and 6,234 children.
Mr Onyeuko said that the troops of Operation Hadin Kai had sustained aggressive posture with vigour in the North East, which had yielded significant results in the last two weeks.
He said that the series of land and air operations conducted in different locations across the North East theatre had reduced the operational capabilities of the insurgents with several of them being neutralized.
Mr Onyeuko said several others were arrested alongside their informants and logistics suppliers, while more terrorists had continued to lay down their arms and surrender to the troops with their families.
