Lagos: Nigerian troops have rescued 1,880 civilians from a Boko Haram redoubt in the restive northeast in the past week and arrested hundreds of insurgents, a military commander said.
The Sambisa forest, covering about 1,300sq km, is a stronghold of the notorious jihadist group, who kidnapped more than 200 schoolgirls in 2014.
"During our operations in the period 14-21 December 2016, a total of 1,880 civilians were rescued from Boko Haram enclaves," Major-general Leo Irabor said.
Irabor added: "564 Boko Haram terrorists were arrested while 19 others surrendered to our troops. Also, seven suspected kidnappers and 37 foreigners were equally arrested."
He said several Boko Haram fighters were killed and a cache of arms and ammunitions was discovered in the operation, part of a military campaign launched last year to clear the area of the jihadists.
Hundreds of civilians, including women and children, have also been freed in neighbouring Cameroon, said Irabor. Eight jihadist suspects were subsequently identified among them and taken into custody.
Boko Haram seeks to impose an Islamic legal system in Nigeria's mainly-Muslim north.
It has been blamed for the deaths of at least 20,000 people since 2009.
The rebellion has also displaced some 2.6 million people, sparking a humanitarian crisis in the region.
The United Nations has warned that the affected region faces the "largest crisis in Africa".
The UN estimates that 14 million people will need outside help next year because of the ongoing violence, particularly in Borno State in northeastern Nigeria, the country's jihadist heartland.
Since early 2015, Nigerian military with the support of a regional force, have recaptured a swathe of territory from the insurgents.
But sporadic attacks on civilian soft targets have continued in the volatile region, including the use of female suicide bombers.
On December 9, two female suicide bombers killed 45 people and wounded 33 others when they detonated their explosives in a crowded market in Madagali, which has been previously targeted.
While there was no immediate claim of responsibility, the blasts bore all the hallmarks of Boko Haram.
Boko Haram is also active in Chad, Niger and northern Cameroon. The group was led by Abubakar Shekau until August 2016, when he was succeeded by Abu Musab al-Barnawi.
The group had alleged links to Al Qaeda, but in March 2015, it announced its allegiance to ISIL.
Since the current insurgency started, it has killed 20,000 and displaced 2.3 million from their homes and was ranked as the world's deadliest terror group by the Global Terrorism Index in 2015.
