The Russian Defense Ministry has shared a video showing the Rostov-on-Don submarine firing a Kalibr cruise missile at targets in Syria.
The Ministry claims that the missile hit an IS target in Raqqa.
The use of cruise missiles prompted a question about their cost this morning by a reporter to Russian Prime Minister Medvedev, who said the budget for the Syria operations was "a secret."
Russian Prime Minister Dmitry Medvedev has refused to name the sum spent by the Russian military for its operations in Syria.
"That's a secret," Medvedev said, according to Russian government daily Rossiskaya Gazeta.
Medvedev was answering a question from a reporter about the cost of the use of Russian cruise missiles in Syria.
Medvedev said that the cost of the operation was within the budget and the Defense Ministry has not asked the government for additional funds for Russia's operations in Syria.
Russian President Putin has invited British specialists to help decipher data from a flight recorder that Moscow believes is from the downed Su-24 jet.
Putin made the suggestion during a telephone call earlier today with UK Prime Minister David Cameron, TASS reports.
Russian Defense Minister Sergei Shoigu gave the flight recorder -- which Russia said yesterday had been found in Syria -- to Putin.
Turkey downed the Su-24 on November 24 near the Syrian border. Ankara insists the jet had violated its airspace while Russia has maintained that it never left Syrian air space.
A Chinese official has denounced a call by the Dalai Lama for dialogue with the IS group, China's state-run Global Times newspaper has said.
"By saying, 'listen, understand and respect' them, it exposes, in his very bones, his sympathy or endorsement for IS," the paper quoted Zhu Weiqun, chairman of the ethnic and religious affairs committee of the top advisory body to China's parliament, as saying.
U.S. Secretary of State John Kerry has said he would travel to Moscow next week for talks with Russian President Vladimir Putin on a political settlement in Syria, Reuters reports.
Reuters adds that Kerry said during an event on the sidelines of the Paris climate talks that despite its military and political interests in Syria, Moscow "has been constructive" in trying to find a political settlement to end the Syrian conflict.

Report: California Shooters Financed Massacre With $28,000 Loan
A married couple who killed 14 people in California last week financed their shooting rampage with a $28,500 loan from an online lender, investigators said on December 8.
About two weeks before attack, the sum was deposited into the bank account of Syed Rizwan Farook, 28, who obtained the loan from San Francisco-based Prosper, an online lending service that arranged the financing through WebBank.com.
The method of financing the crime appears to be unique and unprecedented.
Farook reportedly withdrew $10,000 of the loan proceeds on November 20 and may have used the money to purchase two AR-15 semiautomatic weapons used in the attack from a friend and distant relative, Enrique Marquez.
In addition, in the days before the attack, at least three transfers of $5,000 were put into the account of Farook's mother, Rafia.
The couple left their infant daughter in the custody of the grandmother before going on the shooting spree.
The Kremlin is reporting on its website that Russian President Vladimir Putin has spoken by telephone with British Prime Minister David Cameron.
The two leaders discussed issues relating to the Syrian conflict, the Kremlin says.
"It was noted that Russia and the UK have similar approaches regarding the threat posed by the IS group and other terrorist groups in the region. In this context, issues of establishing bilateral cooperation regarding various government agencies were discussed," the Kremlin said in a statement on its website.

The BBC says that French Prime Minister Manuel Valls did not name the man but has not disputed reports naming him as Mohamed-Aggad.

Russia's TASS news agency has a text transcript of Russian Prime Minister Dmitry Medvedev's remarks this morning including a full quote of his comment about the downing of the Russian Su-24 jet by the Turkish air force on November 24.
"Turkey violated all the norms of international law and gave the grounds for a military response, but the Russian leadership did not go ahead with this," Medvedev was quoted as saying at 13.10 p.m. Moscow time, 10.10 a.m. GMT.
Russian Prime Minister Dmitry Medvedev said this morning that Turkey had given "reasons for the outbreak of a war" when it downed a Russian Su-24 jet on November 24 near the Syrian border, RIA Novosti reports.
