Nigerian soldiers have killed 13 suspected members of Boko Haram.

Official sources said on Friday that the Nigerian forces arrested about 15 people during a raid on a Boko Haram camp located near the states of Borno and Adamawa in northeastern Nigeria.

“Two were arrested on (Thursday) while 13 others were arrested today (Friday) while 13 of them died following a raid on their makeshift camp,” said major general Chris Olukolade said.

Olukolade also stated that some of the people who had fled a previous raid carried out by the Nigerian forces had been arrested in Borno’s capital, Maiduguri, and areas surrounding the city.

This comes a day after Nigeria announced that the Boko Haram had carried out attacks in three different locations, including a college in Adamawa, killing at least 43 people. Most of the victims were reportedly students.

The Boko Haram, whose name means “Western education is forbidden,” says its goal is to overthrow the government in Nigeria.

Since 2009, the Boko Haram has claimed responsibility for a number of deadly attacks in various parts of the African country.

As a result of violence, the government of Nigeria declared emergency rule in the three states of Adamawa, Borno, and Yobe in May 2013.

According to the United Nations, unrest in Nigeria has forced nearly 300,000 people, mostly children, to flee their homes in the three states.
