Twin Blasts at Mosque in Northern Nigeria Kill at Least 24

A pair of explosions killed at least 24 worshippers at a mosque in northeastern Nigeria, with many of the victims caught in the second blast while trying to flee, police said Tuesday.

The attack in Mubi town came a day after President Muhammadu Buhari met with U.S. President Donald Trump at the White House and discussed the threat from the Nigeria-based Boko Haram extremist group. Its fighters were quickly blamed for Tuesday's blasts.

This is the second time in six months that dozens have been killed in an attack on a Mubi mosque. In November, a teenage suicide bomber attacked worshippers as they gathered for morning prayers, killing at least 50 people in one of the region's deadliest assaults in years.

"As I am talking to you now, 24 persons are confirmed dead and the scene is cordoned off by anti-bomb squads and other security personnel," said Adamawa state police spokesman Othman Abubakar.

One resident, Isa Danladi, said he had been about to leave his house near the mosque when he heard the blast.

"The mosque roof was blown off and the prayer was midway when the bomber, who was obviously in the congregation, detonated his explosives," Danladi said. "This is obviously the work of Boko Haram."

Many of the wounded were receiving treatment at hospitals, he said. It was not immediately clear how many people were wounded.

Haruna Hamman Furo, the head of the Adamawa state emergency management agency, described the attack as "devastating."

Boko Haram briefly took over Mubi in late 2014 as its fighters rampaged across northeastern Nigeria, seizing towns and villages in its quest to establish a hard-line Islamic state.

The military and civilian militia ousted the extremists from the town, which is a commercial hub near the border with Cameroon.

In recent months, Boko Haram activity has been concentrated in the far north of Adamawa state, around Madagali, near the border with Borno state. That area is not far from the Sambisa Forest area where the extremists had a stronghold.

Boko Haram fighters are also said to be hiding in the Mandara mountains to the east near Cameroon.
