A Lebanese man has been arrested in the airport of the Nigerian city of Lagos for trying to smuggle drugs to Lebanon in his boxer shorts, the head of the National Drug Law Enforcement Agency (NDLEA) said Wednesday.

Yves Awad, 23, was apprehended by officials of the Federal Airport Authority of Nigeria (FAAN) with about 260 grams of cocaine at the Murtala Mohammed International Airport.

Fifteen people were killed when Boko Haram attacked a remote village in northeast Nigeria, opening fire and burning homes to the ground, three residents told AFP on Tuesday.

The attack happened at about 2:00 pm (1300 GMT) on Monday in Huyum, in the Askira-Uba district of Borno state which locals say has been hit repeatedly in recent weeks by the Islamist militants.

Military top brass from Nigeria and surrounding countries met Tuesday to thrash out plans to take on Boko Haram, as new Nigerian President Muhammadu Buhari takes early steps aiming to defeat the militants.

Chiefs of defence staff from Nigeria, Niger, Chad and Cameroon and a high-level military official from Benin held talks in Abuja to determine strategies for a new, African Union-backed regional force against the rebels.

Spanish police said Monday they had dismantled a trafficking ring they said used voodoo rituals -- including animal sacrifice -- to force Nigerian women into prostitution in Spain.

Six traffickers were arrested and four of the victims freed, police said in a statement.

Nigeria's military on Monday said it had begun shifting the command center for its battle against Boko Haram from the capital to Maiduguri in the northeast, following a directive from President Muhammadu Buhari.

Buhari announced the move in his inaugural speech on May 29, saying the Islamist insurgents would not be defeated until military command and control was transferred to the city at the heart of the uprising.

A female suicide bomber killed two people and injured four others in northeast Nigeria, while two people were injured when a bomb exploded near a military checkpoint, police said on Sunday.

"A female suicide bomber detonated an improvised explosive device strapped to her body along the Baga-Monguno highway, killing herself and two others on Saturday," said Borno state police commissioner Aderemi Opadokun.

The U.N. rights chief on Friday denounced rights abuses by both Boko Haram Islamists and the Nigerian military and asked the country's new president to punish offenders.

"Civilians in northeast Nigeria have been living through horrifying acts of cruelty and violence by Boko Haram. These include wanton killings, summary executions, forced participation in military operations –- including the use of children to detonate bombs, forced labor, forced marriage and sexual violence, including rape," Zeid Ra’ad Al Hussein said.

Two blasts rocked northeast Nigeria on Thursday, killing at least six, after new President Muhammadu Buhari urged closer regional cooperation to defeat Boko Haram.

The first explosion happened in the Borno state capital, Maiduguri, which has been hit by a spate of bombings in recent days, when a truck carrying firewood rammed into a checkpoint outside a military barracks.

The death toll from a blast in the northeast Nigerian city of Maiduguri has risen to 18, a civilian vigilante assisting the military against Boko Haram told AFP on Thursday.

"We retrieved 18 dead bodies from the scene and many people with injuries," Danlami Ajaokuta said of the explosion on the city's Baga Road, which happened at about 5:30 pm (1630 GMT) on Wednesday.

Nigeria's new president, Muhammadu Buhari, on Wednesday promised to look into an Amnesty International report urging the International Criminal Court to probe senior military officers for war crimes in the battle against Boko Haram.

"I assure you that your report will be looked into," an official statement quoted Buhari as saying in Niger's capital Niamey, in his first reaction to the group's 133-page report.
