Suicide bombers killed 28 people and wounded 65 in an attack on a market in Cameroon, Reuters reports. Nigerian-based terror group Boko Haram (WTF is Boko Haram?) is suspected of being behind the attack.

The bombing took place in the town of Bodo, which borders Boko Haram strongholds in northeastern Nigeria.

Suicide attacks have become increasingly common in Northern Cameroon. On Jan. 13, an attack on a mosque in the town of Kouyape killed 13.  In late December, two female suicide bombers blew themselves up at Bodo’s town entrance.

Boko Haram violence has also spread into Chad and Niger. The terror organization has killed thousands and displaced more than two million people over the last six years.
