The Nigerian air force has bombed several insurgent positions in recent days, killing a number of Boko Haram militants, officials said Wednesday.

Several different locations in Borno state were bombed last week on three different days, resulting in the deaths of an undetermined number of Boko Haram terrorists, news reports said.


Bombs were dropped on positions in Kadari, Ngoshe and area near Kangarwa, Nigerian officials said.

Nigeria's government has gradually begun to reacquire ground seized by militants in recent months.

Officials said the bombings, which occurred between Nov. 16-19, were the result of surveillance and reconnaissance intelligence.

Boko Haram has been active in Nigeria for years, as well as neighboring countries, and was the group responsible for kidnapping more than 200 schoolgirls in 2014. Most of those girls remain unaccounted for.

The group, officials say, is responsible for as many as 20,000 deaths and displacing another 2 million people.
