After losing major strongholds and key urban areas across Syria, including its self-proclaimed capital, the city of Raqqa, the Islamic State group now controls only 5 percent of the country's territory, according to Russia's defense minister.
That's a dramatic decline from the height of the rise of IS in 2014, when the extremist group seized about a third of both Syria and Iraq, before its downfall began.
The remarks by Defense Minister Sergei Shoigu came as Russia-backed Syrian troops are pushing deeper into the eastern Syrian town of Mehkan, one of the few still held by IS.
