"The members of the Security Council condemned in the strongest terms the continued escalation of attacks perpetrated by Boko Haram terrorists, including on 13 February in Ngouboua, Chad, against civilians, which killed many persons," the Security Council said in a statement.
The Security Council stressed the importance of bringing the attackers, as well as the organizers and sponsors of terrorist acts to justice.
"The members of the Security Council reaffirmed that terrorism in all its forms and manifestations, including the actions of Boko Haram, constitutes one of the most serious threats to international peace and security," the statement said.
The group started carrying out attacks outside of Nigera in recent days. Earlier this month, the group attacked neighboring Niger and Cameroon, killing as many as 70 people in the latter attack.
Earlier this month, the African Union announced the deployment of an 8,750 strong-force from Nigeria and countries of Niger, Cameroon, Chad and Benin, in efforts to combat the Boko Haram Islamist group.
The Boko Haram extremist group formed in 2002 but began large-scale attacks in 2009, with the aim of establishing an Islamic state with strict Sharia law. Since 2009, the group has expanded its activity across the northeast of the country, killing over 5,000 people, and displacing over a million.
