Takfiri Boko Haram militants from Nigeria have killed at least 92 Chadian soldiers in an attack on an army base on the border with Chad.

Axar.az reports citing PressTV that the deadly attack took place in Boma, in western Lac Province, early on Monday, and lasted around seven hours.

“We lost 92 of our soldiers, non-commissioned officers and officers,” Chadian President Idriss Deby Itno said on Tuesday, after visiting the site of the attack.

“It’s the first time we have lost so many men,” he said.

An unnamed soldier said the Boko Haram militants destroyed 24 military vehicles, including armored vehicles, and carried off captured weapons in speedboats.

“The enemy has hit at our defenses hard in this zone,” a senior officer said.

Boko Haram militants hailing from northeast Nigeria have been stepping up their attacks on the Lake Chad region in recent months.
