Syria - Syrian government troops launched a ground offensive Wednesday in the country's central region under cover of Russian airstrikes, a Damascus official said. And in the first salvo from the sea, Russian warships fired missiles into Syria, with Moscow saying they were targeting militants.
The latest developments, exactly a week after Russia began launching airstrikes in Syria, add a new layer to the fray in the complex war that has torn this Mideast country apart since 2011.

Moscow has mainly targeted central and northwestern Syria, strategic regions that are the gateway to President Bashar Assad's strongholds in Damascus, and along the Mediterranean coast. But the strikes appear to have given Assad new confidence to try to retake some lost ground.
According to the Syrian official, the government push is concentrated in the adjacent provinces of Hama and Idlib where rebels have been advancing in the past months. The official spoke on condition of anonymity in line with regulations.
The Islamic State group is not present in the areas where the fighting is underway.
Wednesday's offensive in central Syria and the ensuing clashes with militants, including al-Qaida's Syrian branch, was the first major ground fighting since Moscow began launching air raids in Syria last week.
The Russian airstrikes appear to have emboldened Syrian troops to launch the ground push after suffering a string of setbacks in northwestern Syria over the past few months.
In Moscow, Russian Defense Minister Sergei Shoigu said Russia is using warships in the Caspian Sea to target the Islamic State group in Syria. Shoigu told President Vladimir Putin in televised remarks that Russia on Wednesday morning carried out 26 missile strikes from four warships of its Caspian Sea flotilla. Shoigu insisted the operation destroyed all the targets and did not launch any strikes upon civilian areas.
Shoigu also said Russia has carried out 112 airstrikes on IS positions since its operation began on Sept. 30.
The Britain-based Syrian Observatory for Human Rights said a government offensive began on four fronts early Wednesday in the northwestern provinces of Idlib and neighboring Hama. Observatory director Rami Abdurrahman described it as "the most intense fighting in months."
In Syria, the leader of a U.S.-backed rebel group, Tajammu Alezzah confirmed the ground offensive in a text message to the media, claiming there were Russian and Iranian soldiers in the operation.
The rebel group's commander, Maj. Jamil al-Saleh, said the offensive, accompanied by air cover and shelling, came from three fronts, including Latamneh, north of the Hama province where his group is based, and Kfar Zeita to the north. The offensive targets the rural part of northern Hama and Idlib, the northwestern province, almost totally controlled by rebel groups, he said.
Activist Ahmad al-Ahmad, who is currently in Idlib, said government troops are "heavily" shelling central areas after rebels attacked an army post and destroyed a tank there.
The Observatory, which has a network of activist on the ground, and al-Ahmad said the main launching point for government forces is the town of Morek on the highway that links the capital, Damascus, with the northern city of Aleppo, Syria's largest city and former commercial center. Rebels have controlled areas on the highway since 2012.
The Local Coordination Committees, another activist group, said rebels were able to destroy two tanks and an armored personnel carrier in northern parts of Hama province near Idlib.
The Observatory said a total of 37 Russian air raids areas hit the area of fighting on Wednesday alone.
The Observatory said two helicopters, believed to be Russian, were seen flying at low altitude in Morek. It added that militants opened fire at the helicopters without striking them. It was not immediately clear if the pilots were Russian or Syrian. The Syrian military has Russian-made helicopters in its air force.
Though the Islamic State has no presence in the areas hit Wednesday, al-Qaida's affiliate in Syria, the Nusra Front, is active in central and northern parts of the country, as are the Western-backed rebels.
In Turkey, Prime Minister Ahmet Davutoglu renewed criticism of Russia's airstrikes in Syria, insisting they were mainly targeting the moderate Syrian opposition and therefore helping strengthen IS. He asked that Russia also respect Turkey's security concerns over Syria.
Davatoglu called on Russia to respect Turkey's air space, saying the country would not "make any concessions" on matters concerning its border security.
Russian warplanes violated Turkey's borders on two separate occasions over the weekend, drawing strong protests from Turkey's NATO allies. Turkey scrambled F-16s in response and also summoned the Russian ambassador to lodge protests.
Earlier, Turkey's Foreign Ministry said Turkey had proposed a meeting between Turkish and Russian military officials to be held in Ankara on avoiding future Russian infringements of Turkey's airspace.
Also Wednesday, Syrian state TV quoted an unnamed Syrian military official as saying that Russian warplanes attacked Islamic State positions in the town of Al-Bab and the nearby town of Deir Hafer in the northern province of Aleppo.
