Abuja - Nigerian troops killed four suspected Boko Haram suspects and set free 61 people, mainly women and children, held by the jihadist group in the flashpoint northeastern Borno state, the army said Thursday.
In an operation, troops under air cover cleared Boko Haram camps "and in the process rescued 61 persons abducted and held captive by the Boko Haram terrorists," the army said in a statement.
"The rescued persons were mainly women and children," the military said, adding that troops also "killed four terrorists and arrested one."
The army had last October 28 also said it freed more than 330 people, mostly women and children, from Boko Haram's Sambisa forest stronghold in an operation in the volatile northeast.

Of the survivors, 192 were children while 138 were women.
There was no independent confirmation of the army claims.
The military has in recent months claimed a string of successes against Boko Haram in its quest to end the hardline Islamist group's six-year insurgency.
In early August, the army said it had freed 178 people, including more than 100 children, following an operation near Aulari town, about 70 kilometres (44 miles) south of Maiduguri, the capital of Borno State.
President Muhammadu Buhari, who came to power in May on a pledge to crush Boko Haram, has given his military commanders until the end of December to defeat the rebels.
