Eight were killed and five wounded after a terrorist attack on a job site in the West African Nation of Niger operated by mineral driller Foraco International.

According to a release by the French company, terrorists entered the camp at 2 a.m. local time and attacked a building where team members were sleeping. Seven of those killed were employees while the eighth was a government employee. Five others were injured, with two in serious condition. The company is drilling two deep water wells for Niger’s Ministry of Water.

According to reports, local authorities are blaming terrorist group Boko Haram for the attack. The group, whose name translates to “western education is forbidden,” has been carrying out attacks in the area since 2009.
