Ten Boko Haram militants (pictured) were executed by the Chadian government, after they were found guilty of attacking the capital earlier this year, reports the BBC.

In June, Nigerian Islamic militants Boko Haram made good on their promise to attack neighboring nation Chad for their partnership with the Nigerian military.

As Face2Face Africa previously reported:

On Monday, alleged terrorists riding on the backs of motorcycles entered N’Djamena, reportedly blowing themselves up.

According to Al Jazeera, the attack took place as police cadets were being trained at a nearby academy.

The capital’s first attack resulted in 27 casualties as well as more than 100 injured.

A month later, Boko Haram would strike again with an explosion at a market also located in the capital.

Fifteen people were killed.

At the time, Chadian Communications Minister Hassan Sylla Bakara warned that Boko Haram had “made a mistake targeting Chad,” because the group would soon be “neutralized.”

Chad also made good on their promise Monday morning.

The 10 were convicted of criminal conspiracy, murders, willful destruction with explosives, fraud, using psychotropic substances, and illegal possession of arms and ammunition, according to Chief Prosecutor Bruno Mahouli Louapambe.

Among the 10 was Mahamat Mustapha (pictured), a.k.a. Bana Fanaye, who was known as the “mastermind” of the first attack.

While the death penalty was initially not in use in Chad, by July, it was reinstated for acts of terror.

Consequently, the 10 were executed in Massaguet, 40 miles northeast of N’Djamena. About the shooting, a source reportedly told Reuters, “They were shot this morning at the Massaguet firing range.”

Chad has been a strong partner of Nigeria’s offensive against Boko Haram.

Since joining forces, the Chadian military has helped recover the nearly 15 territories seized by Boko Haram in northern Nigeria as well as help weed them out of the Sambisa Forest.
