Boko Haram kills 33 security personnel in Nigeria attacks, sources say

Militants with Islamist terror group Boko Haram killed at least 33 security personnel in attacks this week on a military base and a police station in northeastern Nigeria's Yobe state, security sources said Wednesday.

Monday night's attacks in the town of Buni Yadi killed 18 soldiers and 15 police, the sources said.

"There were attacks by Boko Haram insurgents in Buni Yadi, but details are still sketchy," Yobe state police commissioner Sanusi Rufa'i said.

The attacks come more than a month after the group abducted an estimated 276 girls from a boarding school in Chibok, also in northeastern Nigeria. Dozens escaped, but more than 200 girls still are missing.

Boko Haram translates as "Western education is a sin" in the Hausa language. The militant group says its aim is to impose a stricter enforcement of Sharia law across Nigeria, Africa's most populous nation, which is split between a majority Muslim north and a mostly Christian south
