Vladimir Putin has ordered the withdrawal of Russian troops from Syria, Moscow's state news agencies are reporting.
The Russian leader made the announcement at the Hemeimeem air base in Syria's coastal province of Latakia, the heartland of Syrian President Bashar Assad's Alawite minority.
Accompanied by defence minister Sergey Shoygu, Mr Putin said Russian and Syrian armies had destroyed "one of the most capable groups of international terrorists" in just over two years.
He said the two countries' forces would respond with power strikes if "terrorists raise their heads" in Syria.
The visit marks Mr Putin's first trip to Syria and comes as the Assad regime's forces have retaken control over most of Syria under Russian air cover.
The air base has served as the main foothold for the air campaign Russia has waged since September 2015 in support of Mr Assad.
