Two suicide bombers killed at least 19 people and wounded 50 others on Friday after they targeted a marketplace in Meme, western Cameroon, located near the shared border with Nigeria, security sources said. The timeline for the incident is unclear, but officials know how the attack unfolded. One official revealed the blasts occurred when two militants with explosive devices in tow walked into the market and blew themselves up, according to the Xinhua News Agency.

Ten people were reported to have died in the initial blast and several others were injured. However, some of those injured succumbed to their injuries at the hospital, bringing the toll to 19.

There has been no claim of responsibility for the attack, but officials have placed the blame on Nigerian-based Boko Haram, which has been responsible for a series of suicide attacks in Cameroon, as well as neighboring Chad and Niger within the past year, according to the Business Standard.

Boko Haram, which recently overtook ISIS as the world's deadliest militant group, have killed about 1,000 people in Cameroon alone, government and military sources say.

The total death toll associated with the group is much higher however, with officials estimating that Boko Haram violence has left more than 15,000 people dead and more than two million others homeless throughout the course of its six-year insurgency, according to Reuters.

Nigeria, Chad, Niger, Cameroon and Benin have set up a regional force tasked with wiping out Boko Haram. The group has been largely successful thus far, driving the extremists from various towns and villages where they announced their Islamic caliphate. In light of this, Boko Haram has been forced to resort to guerilla tactics during terror attacks.
