At least 11 people have been killed in two bomb explosions in a northeastern Nigerian village.

Two female bombers were hiding among residents fleeing a suspected Boko Haram attack before they initiated the blasts, local authorities said on Sunday.

The attack happened in Dar village, in the north of Adamawa state, on Saturday evening, authorities confirmed.

There was no immediate claim of responsibility for the explosions, but authorities said that they bore the hallmarks of the Takfiri militant group Boko Haram.

Meanwhile, soldiers shot dead a suspected bomber outside the main military base in the restive northeastern state of Borno, according to reports.

Bomb explosions have been on the rise in Nigeria. Just on Thursday, at least 34 people were killed in a wave of attacks, while last month hundreds died in explosions across the country.

Nigeria has intensified crackdown on Boko Haram as the terrorist group continues to wreak havoc across the country through bombings, raids, and kidnappings.

Since the beginning of Boko Haram’s bloody militancy in 2009, at least 15,000 people have been killed and 1.5 million others displaced due to the violence perpetrated by the group, whose name means “Western education is forbidden” in the Hausa language, the most commonly-spoken language in Nigeria.

The Boko Haram militancy has also spilled over into several neighboring African nations. Troops from Nigeria, Chad, Cameroon and Niger have been battling Boko Haram terrorists in recent months.

The terrorists have recently pledged allegiance to the Takfiri Daesh militant group, which is primarily operating inside Syria and Iraq.
