Nigeria: Boko Haram attacks mosque worshippers

Reports from north-eastern Nigeria say around 150 people have been killed by Boko Haram insurgents.

The killings are said to have happened two days ago, but details are only now emerging because of bad communications.

Witnesses say ninety-seven people were killed in Kukawa village close to Lake Chad.

In a separate attack, outside Monguno town, gunmen attacked as people were praying in the evening.
