Niger: At least 27 persons killed in Boko Haram attack

At least 27 people have been killed in an attack in southeast Niger, local officials said on Sunday.

Other people were wounded and some more reported missing in the assault on Saturday evening in the village of Toumour in the Diffa region, said a senior local official.

Witnesses and other officials confirmed the attack, which came hours before municipal and regional elections went ahead across the country on Sunday.

"Some victims were killed or wounded by bullets, others were burnt inside their houses, consumed by the flames of an enormous fire set by the attackers," said the official.

Between 800 and 1,000 houses, the central market and numerous vehicles were also destroyed in the fire, he added.

Roughly 70 attackers arrived at Toumour at around 1745 GMT on foot, having swum across Lake Chad, said the official. The attack itself lasted three hours.

"They first attacked the residence of the traditional chief, who only just managed to escape," he said.

"It was an attack of unprecedented savagery," said a local elected official who asked not to be named. "Nearly 60 percent of the village has been destroyed."

Diffa a region located on the border with Nigeria, has been frequently attacked by Boko Haram since February 2015.
