Chad's President Mahamat Deby said the decision to terminate the country's military pact with France was taken because it had become outdated, in his first public remarks since the surprise announcement last week.

The decision by Chad is another blow to what remained of France’s military influence in the troubled stretch of countries below the Sahara, where Russia’s influence has been growing.

Chad, a former African colony of France, has for decades been central to its military operations in Africa, but it is developing closer ties to Russia amid the NATO war with Russia in Ukraine.
