Chad announced it would take military action after a deadly drone strike hit the Tina area near its border with Sudan, killing several civilians.
The government described the incident as a grave security breach, warning that any further attacks would face an immediate and decisive military response.
The Chadian presidency said President Mohamed Deby convened an emergency security meeting with senior army and intelligence leaders following the deadly strike.
Officials stressed that the attack constituted a direct threat to national security and required urgent measures to protect civilians and safeguard territorial integrity.
Deby ordered the deployment of defence and security forces along the Sudanese border beginning Wednesday evening, placing troops under heightened operational readiness.
Authorities said forces received clear instructions to respond swiftly to any renewed aggression while reinforcing surveillance across sensitive frontier regions.
The presidency also sent the ministers of defence, security and land administration to the attack site to assess casualties, material losses and humanitarian needs.
Officials linked the incident to instability generated by the ongoing conflict in Sudan, noting that Chad has repeatedly sought to mediate between rival factions.
They warned that armed actors were exploiting social ties between border communities to draw violence into Chadian territory and widen the conflict’s reach.
In a separate statement, the Rapid Support Forces denied involvement and accused General Abdel Fattah al Burhan’s army of carrying out the strike, calling it a violation of Chadian sovereignty.
