Russian President Vladimir Putin spoke by phone with Syrian President Bashar al-Assad on Sunday, congratulating him on his forces retaking Palmyra, the Kremlin said.
The recapture of the ancient city represents a major victory over the Islamic State group, whose fighters had destroyed many monuments at the UNESCO world heritage site since they overran it in May last year.
"In a conversation with the Syrian president, Vladimir Putin congratulated his colleague on Syrian forces liberating the city of Palmyra from terrorists," Kremlin spokesman Dmitry Peskov said, quoted by RIA Novosti state news agency.
