Chad’s ruling military council has rejected an offer to negotiate a ceasefire with rebels who have fought since the unexpected death of President Idriss Dévi.
The military council came to power earlier this week after Mr Debbie was killed in a clash with rebels.
A council led by Debbie’s son said he would oversee the transition to elections for 18 months.
Opposition politicians and rebels have accused the military takeover as a coup.
Debbie, 68, had just won the presidential election when the military announced on Tuesday that it had been fatally injured in a fight against rebels in the northern region of Kanem in Central Africa.
Rebels, known as Chad’s Change and Concord Frontline (FACT), wiped out the north on election day and demanded the end of Mr Debbie’s 30-year rule.
On Saturday, rebels said they were ready to discuss a political solution, but did not support the “coup” that led Debbie’s son, General Mahamat Debbie, into power.
But the next day, the military council said it would not negotiate with rebels during the war.
“It’s not time for mediation or negotiations with outlaws in the face of this situation endangering the stability of Chad and the region as a whole,” Azem Bermendao Agna, a spokesman for the Military Council, said in a statement. Stated.
“They are rebels and that’s why we’re bombing them. We’re at war, that’s it.”
Mr Agna said some of the rebels had fled to neighboring Niger. He then urged authorities to “facilitate the capture and trial of these war criminals.”
He said FACT leader Mahamato Mahdiari was “sought for war crimes” in Libya, where his rebel groups are actively present.
This group was formed in 2016 with the aim of overthrowing the Chad administration and is associated with the recent civil war fighting in Libya.
The military council is under pressure to transfer power to the caretaker government of civilians as soon as possible. The African Union Peace and Security Council has expressed “grave concern” about military takeover, but France and regional powers are pushing for a civilian and military solution.
Debbie was buried on Friday at a state funeral attended by French President Emmanuel Macron and thousands of Chadians.
A trained army officer, Debbie came to power through an armed uprising in 1990. He was a longtime ally of France and other Western nations in the fight against jihadist groups in the Sahel region of Africa.
