Gunmen opened fire on a police helicopter which raided a camp of the Ansaru militant group in Kaduna state on Wednesday.
Frank Mba, police spokesman, disclosed this in a statement, saying the group lost 250 fighters.
He said the operation started in the early hours of the day in an operational camp of the group located in Kuduru forest, Birnin Gwari.
According to Mba, the militants used “sophisticated anti-aircraft rifles and GPMG” during the attack.
“Commendably, the pilot and the co-pilot who demonstrated uncommon courage and expertise, successfully landed the aircraft at the Air Force Base, Kaduna without further incident,” he said.
