The Chadian government has announced it will send troops to Cameroon to help fight Nigerian terror group Boko Haram's insurgency.
The announcement came a few days after Cameroonian troops said they killed some 143 Boko Haram fighters after they ambushed a military camp in Kolofata, some 1,200km from the capital Yaoundé.
Cameroon's President Paul Biya said in a statement: "[Chad President Idriss Deby Itno] has decided to send a large contingent of Chadian armed forces to help the Cameroonian Armed Forces facing... repeated attacks from the Boko Haram terrorist sect".
It is not clear yet how many troops Chad will send to Cameroon, Reuters reported.
Boko Haram members attack towns and villages mainly in central and northern Nigeria, along the border with Cameroon, where they have also established an Islamic caliphate.
The group sometimes crosses the Nigerian border and carries out attack in Cameroon, where last September soldiers killed 100 insurgents who attempted to attack a town.
The terrorists, condemned worldwide for kidnapping 220 schoolgirls last April, captured 16 towns at the beginning of January and slaughtered at least 2,000 people, including women and children, in Baga town, Borno state.
The mass-killing was dubbed "possibly the deadliest" committed by the terrorists, believed to have murdered thousand of civilians since their insurgence began in 2009.
