Nigeria’s security challenges following bombings by a radical Islamist sect are holding back some foreign investment in the oil-rich country, President Goodluck Jonathan said on Monday. Boko Haram, whose name means “Western education is sinful”, has claimed responsibility for a series of recent bombings in Africa’s most populous nation, including a blast last month at the U.N. headquarters in the capital which killed 23 people.

“We are worried about the security challenges we are now facing in the country because it is preventing investors coming into the country,” the president said in an interview on local NTA television. “I assure you this situation will be brought under control.”

Boko Haram, which wants sharia law more widely applied across Africa’s most populous nation, has rapidly become Jonathan’s biggest security headache. It has carried out almost daily shootings and attacks with homemade bombs against security services and civilians in its home base in the remote northeast.

Shooting was heard on Monday in Maiduguri, the capital of northeastern Borno state where the sect was founded. Earlier, gunmen bombed a police station and robbed a bank in the northern town of Misau, in a similar attack to others carried out by Boko Haram.
