On-the-run extremists in revenge killings

Scores of people have been shot and burned to death after Boko Haram Islamic extremists on the run from a three-nation offensive took revenge on civilians in neighbouring Cameroon, authorities said.

Officials said more than 500 wounded people are trapped in the town of Fotokol, where fighting against Boko Haram began on Wednesday and continued throughout yesterday.

The latest bloodshed comes after Boko Haram warned other nations over uniting against it, and appears to be a direct result of Cameroon and Chad launching an offensive this week.
