Some 200 Boko Haram fighters were killed in the offensive that began Sunday. Additionally, ten Chadian soldiers were killed and 20 wounded.
The offensive opened up a new front in the regional effort to wipe out the Islamist group, whose six-year insurgency has spread across borders.
It also came after Boko Haram leader Abubakar Shekau pledged allegiance to the Islamic State in Iraq and Syria in an audio message at the weekend.
