Ariel footage released on Saturday shows the destruction caused by the Islamist militant group Boko Haram on a village in Chad a day earlier.
Arriving by motorboat in the middle of the night, the rebels set houses ablaze and attacked a police station in Ngouboua on Lake Chad.
Several people were killed.
The attack was Boko Haram’s first strike on Chad. They already control a large area of northwestern Nigeria after deadly attacks on several cities and towns.
Bayana Kossingar, the regional governor said:
“We knew it would happen eventually. But this will never happen again. We have troops coming in to protect the region. Once the area is secure, people will come back and they will stay.”
On Saturday, Nigerian troops repelled the latest violence by the jihadists on the city of Gombe.
Nigeria has postponed a presidential election, thathad been due on Saturday, for six weeks, citing the security threat from the militant group.
Boko Haram seeks to carve out an Islamist emirate around the borders of Nigeria, Chad, Cameroon and Niger.
