At least 10 people have been killed in northeast Nigeria in a bombing attack carried out by a girl believed to be 12.

According to reports, the girl detonated her explosives at a market in the area of Wagir, in the Gujba district, south of Damaturu, the capital of Yobe State, on Tuesday.

At least 30 other people were reportedly injured in the deadly attack.

In a similar incident on Monday, two teenage female bombers detonated their explosives near a crowded mosque in the northeastern Nigerian city of Maiduguri, killing about 30 people.

Reports said that many were injured in the attacks.

No group has claimed responsibility for the bombings; however, the Takfiri Boko Haram group has claimed responsibility for a number of deadly attacks and bombings in various parts of Nigeria during the past six years.

Boko Haram, which has pledged allegiance to the ISIL Takfiri group, which itself primarily operates inside Iraq and Syria, started its campaign of terror in Nigeria in 2009 and has recently expanded its terrorist activities to Nigeria’s neighboring countries as well.

Boko Haram militancy over the past years has claimed the lives of some 15,000 people and displaced around 1.5 million others.

The Nigerian military says the extremists have been confined to the Sambisa Forest in the northeastern part of the country.

Boko Haram means “Western education is forbidden.”
