MOSCOW (Sputnik) — Protesters are holding the flags of Russia and Syria, and various placards condemning Turkey's actions.
According to the organizers, the rally involves about 500 people.
"All of them are Muscovites, adults, youth, members of the Russian Liberal Democratic Party. They all came to express their position on the incident with our Su-24," the coordinator of the Moscow branch of the Liberal Democratic Party, Boris Chernyshov, said.
The police have called on protesters to calm down. No protester has been detained, and law enforcement has been deployed near the embassy.
Some cars passing through the streets are honking in support of the protesters.
On Tuesday, a Russian Sukhoi Su-24 jet crashed in Syria. Russian President Vladimir Putin said that the plane was downed by an air-to-air missile launched by a Turkish F-16 jet over Syrian territory, falling 4 kilometers (2.5 miles) from the Turkish border. Ankara claimed it downed the Russian plane because it violated Turkish airspace. Moscow has firmly denied the accusations.
Putin described the Turkish attack as a "stab in the back" carried out by "accomplices of terrorists."
