Syrian state media say shells have hit the Russian embassy in Damascus causing material damage.
State news agency SANA said two shells were fired at the Russian embassy Sunday, one hitting the compound while the other fell nearby.
Syrian rebels in the suburbs of the capital have previously struck the Russian embassy.
Moscow is a strong supporter of President Bashar Assad and has been involved in the six-year war since September 2015.
