As soldiers continue an offensive against radical Islamic extremists in northeast Nigeria, young men armed with machetes and sticks have now entered the streets of the region's biggest city, targeting suspected fighters.

The members of the "Civilian JTF," a play off the acronym used to describe the joint military and police taskforce in the region, already have come under attack from extremists for pointing out suspects to soldiers. However, it remains unclear what happens to those the group points out, as some suspects in Maiduguri have already been shot dead by security forces.

The vigilante movement comes after President Goodluck Jonathan declared a state of emergency May 14 in three northeastern states, giving security control to the country's military in hopes of routing the extremists.
