Chad's transitional government has vowed to more than double the size of its army by the end of 2022 to deal with security challenges, including threats from militants.
Boko Haram militants have killed at least 10 Chadian soldiers in an attack on a military unit in Lake Chad province near the Nigerian border, Chad's government said in a statement.
Militants attacked early on Tuesday morning, killing around 10 men and wounding several others, the statement said.
The unit had been dispatched as a precursor to setting up an army post on the island of Bouka-Toullorom, between the villages of Ngouboua and Kaiga, where Boko Haram has carried out several offensives in recent years.
The Boko Haram insurgency, which erupted in northeast Nigeria in 2009, has killed more than 350,000 people and forced millions to flee their homes.
