Troops also seized seven vehicles and 13 telephone handsets, as patrols moved “to secure towns and villages from infiltration,” while enforcing curfews in areas deemed potentially dangerous, the ministry said Sunday. A day earlier, the ministry trumpeted a weapons seizure that included rocket-propelled grenade launchers..

Among those targeted by the military was the Islamist militant group Boko Haram.

The military said its forces stopped an attempt by fleeing Boko Haram insurgents to infiltrate Maiduguri, the capital of Borno state, in northeastern Nigeria.

Much of the violence over recent years has been blamed on Boko Haram, the name of which means “Western education is sacrilege.”

On Friday, a spokesman for the U.N. human rights commissioner told reporters that Boko Haram could face war crimes charges for alleged ethnic and religious cleansing in Nigeria.

Addressing reporters in Geneva, Rupert Colville urged it and other extremist groups to stop “cowardly attacks” against civilians, security forces, Nigerian officials and foreign nationals.

According to Human Rights Watch, the group has killed more than 2,800 people in an escalating campaign to impose strict Islamic law on largely Muslim northern Nigeria.

Nigeria is Africa’s most populous country, with a population of nearly 175 million according to the CIA World Factbook, and is the political and economic powerhouse of West Africa.
