The fight against the extremist group has shifted territory, as Chad, Cameroon, and other neighbours of Nigeria are feeling their wrath now.

Twin blasts by Boko Haram hit Northern Cameroon on September 3, killing nineteen and wounding over one hundred and forty people.

The blasts occurred in the Kerawa region, where Cameroon’s military is locked in deadly battles with the group.

The first explosion on Thursday went off just after 0900 local time (0800 GMT) in the market in Kerawa, BBC reports.

The second was detonated soon afterwards, about 200m (218 yards) from the military infantry camp, an army officer based in the north told Reuters.

Other reports say at least 30 people were killed.

A local government official told Reuters that the attacks were carried out by female bombers although there has been no independent confirmation of this.
