The two presidents met in Moscow on Wednesday as Russia tries to boost its influence in Africa.

Mr Déby seized power after his father was killed by rebels in 2021.

The junta initially promised an 18-month transition to elections, but then delayed them until October this year.

Last December, the group held a controversial referendum on a new constitution that critics say could help cement Mr Déby's power.

About 86% of Chadians who took part voted in favour of the new constitution, according to the government commission that organised the poll.

On Wednesday, Mr Putin told Mr Déby: "We are glad that it was possible to hold a referendum on the constitution.

"I am confident that the elections will be held at a high level in the near future. We are glad that you have managed to stabilise the situation in the country."

Russia has been building close ties with Mali, Burkina Faso and Niger - all of which are now under military control and have cut ties with former colonial power France.
