According to Global News Nigeria, ten members of the Islamist militant group Boko Haram have been executed by firing squad in Chad.
It comes a day after they were found guilty of terror charges at a trial in the capital N'Djamena.
Security sources said they were shot at a firing range norh of the capital.
All 10 were convicted over their roles in twin attacks on the capital in June, which killed at least 38. A month after the attack, Chad reintroduced the death penalty for acts of terror.
"They were shot this morning at the Massaguet firing range," a source told Reuters news agency, referring to a city about 60km (40 miles) north-east of N'Djamena.
