Members of the Canadian Forces are in a Niger town that was attacked by Islamist extremist group Boko Haram on Monday, CTV News has learned.

Canadian Special Operations Forces are in the town of Diffa, where they are participating in a military exercise, CTV’s Mercedes Stephenson reported late Monday night.

They are unharmed and believed to be safe.

Boko Haram is believed to be responsible for a car bomb that exploded in Diffa at around 3 p.m. Monday. There was no immediate death toll for the attack, which took place near a customs office.

The Canadian Forces members are in Diffa as a part of Exercise Flintlock, an annual military exercise designed to help African militaries co-operate and build the capacity to fight terrorism.
