An attack on Chad’s presidential palace left 18 assailants dead and six in custody, with one soldier killed and three wounded, state media reported Thursday.

The attack on Wednesday night occurred while Chadian President Mahamat Deby Itno was inside the palace, but authorities said the situation was quickly brought under control.

“The situation is completely under control. There is no fear,” Foreign Affairs Minister Abderaman Koulamallah said while surrounded by soldiers in a live Facebook broadcast filmed inside what appeared to be a quiet presidential palace late Wednesday.

In an interview with state TV, Koulamallah praised the vigilance of the palace guards, describing the attackers as disorganized and intoxicated by alcohol and drugs. When asked if the attack was terrorism, he said it was probably not, as the attackers were local youths from the capital, N’Djamena.

The attack occurred the same day as a visit by Chinese Foreign Minister Wang Yi, who congratulated Deby Itno on reestablishing constitutional order.

In the immediate aftermath, rumors spread online that the attack was the work of Islamic militant group Boko Haram.

Boko Haram, which launched an insurgency more than a decade ago against Western education, seeks to establish Islamic law in Nigeria’s northeast. The insurgency has spread to neighboring West African countries including Cameroon, Niger and Chad.

Chad, a country of nearly 18 million people, has been reeling from political turmoil before and after a controversial presidential election that resulted in Deby Itno’s victory. He had led the country as interim president during the period of military rule that followed the death of his father in 2021.
