The U.N. Security Council is urging immediate stepped up regional military coordination and operations to more effectively combat the Boko Haram terrorist group in Nigeria and neighboring countries.

The council reiterated its "deep concern" in a statement Tuesday that Boko Haram is "undermining the peace and stability of the West and Central African region." Council members condemned the escalating attacks by Boko Haram in Nigeria and against Chadian army soldiers deployed to fight the terrorist group in Cameroon.

The council singled out the Islamic extremist group's recent attacks on Maiduguri, the biggest city in northeast Nigeria, in Borno State and in the Lake Chad Basin region including against the Chadian army.

The council commended the Chadian army's swift assistance in the fight against Boko Haram in Cameroon.
