Boko Haram continues assault on Nigerian city of Maiduguri

Boko Haram insurgents attacked the outskirts of Maiduguri in northeast Nigeria on Sunday, security sources said, their second assault in a week on a city they hope to make the capital of a breakaway Islamist state.

At least eight people were killed as the militants clashed with soldiers, witnesses and a hospital source said.

"There is heavy gunfire going on. Everybody is panicking and trying to flee the area," Idris Abubakar, a resident of Polo suburb on the southwestern outskirts of the city, said.

The insurgents, who arrived in several armed pickup trucks and on motor-bikes, attacked three places in the south ofMaiduguriat around the same time, a security source said.

Troops backed by vigilantes had pushed them out of the southeastern outskirts of the city, a spokesman for a local pro-government vigilante group said.

"The terrorists' attack on Maiduguri in the early hours of Sunday was quickly contained," Nigeria's defence spokesman, Maj.- Gen. Chris Olukolade, said in an emailed statement.

"The terrorists incurred massive casualties. The situation is calm as mopping up operations are ongoing."

Militants threaten stability

GrowingBokoHaramviolence is a big problem for PresidentGoodluckJonathan, who stands in a presidential election on Feb. 14 that analysts say is too close to call.

The electoral commission is struggling with logistics to enable more than a million internally displaced people to vote.

Capturing Maiduguri, the northeast's main city and the place where the insurgency sprang from five years ago, would be a huge victory for Boko Haram, which controls mostly rural areas along the Cameroon and Chad borders that make up a territory the size of Belgium.

Last weekend, the military repelled multiple attacks by militants in Maiduguri in which more than 100 people were killed.

Boko Haram has become the main security threat to the stability of Nigeria, Africa's biggest economy and top oil producer, and increasingly threatens its neighbours. The group has killed thousands of people, many of them civilians, and kidnapped hundreds while the government has struggled to forge an effective response.

Last month, its fighters took control of Baga, on the shores of Lake Chad, the headquarters of multinational force comprising troops from Niger, Cameroon and Chad.

Chadian forces killed 120 Boko Haram militants in a battle in the north of Cameroon, the army said in a statement on Saturday. Three of its soldiers were killed.
