An official has said that at least seven persons kidnapped by Boko Haram on Tuesday have been freed, Premium Times reports.

It was reported earlier that about 10 oil explorers hired by the state oil firm, NNPC, were kidnapped by the terror group, alongside their security aides. The victims were part of the team exploring for crude in the Lake Chad basin.

The council chairman of Magumeri Local Government Area of Borno State, Zanna Modu said that at least seven of the abducted persons including members of the NNPC exploration crew were freed after a rescue-mission embarked upon by a joint force of soldiers and local security personnel.

He said of the abducted persons, the troops were able to rescue four Civilian-JTF members, two NNPC personnel and a staff of the University of Maiduguri. It is not yet clear how many of the abducted oil workers or their security aides still remain with the Boko Haram.
