Moscow: Russia's parliament ratified a treaty with Syria on Friday that allows Russian troops to stay indefinitely in the Mideast country, a show of support for embattled Syrian President Bashar Assad.
The development comes against the backdrop of a Syrian army onslaught on the rebel-held eastern part of the city of Aleppo in northern Syria, which has been backed by Russian warplanes. Since the collapse of a U.S.-Russia-brokered cease-fire last month, ties between Moscow and Washington have grown even more strained.
The two powers support opposite sides in the war - Moscow has been a staunch Assad ally and the United States backs Syrian rebels trying to oust him.
Russia's air campaign in Syria, launched a year ago, has reversed the tide of war and helped Assad's forces regain some key ground. Moscow says the goal of its military operation is to assist the Syrian army in the fight against terrorism. It rejects accusations of targeting civilians.
Lawmakers in the Kremlin-controlled State Duma voted unanimously to approve the deal, which allows Russia to keep its forces at the Hemeimeem air base in Syria's coastal province of Latakia, Assad's Alawite heartland, for as long as it wants. The deal was signed in August 2015 in Damascus, a month before the Russian air campaign began.
Russia also has a naval base in Syria's port of Tartus, the only such outpost outside the former Soviet Union. That base is not covered by the treaty, and some lawmakers say it could be the subject of a separate deal.
On Thursday, the Russian military warned the U.S. against striking the Syrian army, stressing that Russian air defense weapons in Syria stand ready to fend off any attack.
Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov said any U.S. strikes on areas controlled by Assad's government could jeopardize the lives of Russian servicemen, and noted that the range of Russian S-300 and S-400 air defense missile systems would "surprise" any country operating its aircraft over Syria.
During Friday's debates, Russian lawmakers said that Russia should demonstrate its military muscle to deter the U.S.
Leonid Kalashnikov, a Communist lawmaker, said Moscow must "seriously defend our interests in Syria" in a resolute response to what he and other lawmakers described as Washington's anti-Russian policies.
Meanwhile, Syrian rebels said they had captured several Shiite pro-government fighters in Aleppo after repelling a government offensive on a southern neighborhood of the contested city.
Social media postings showed rebels from the Fastiqum faction harshly interrogating three captives, who spoke with Iraqi accents.
The Fastiqum and Nour el-Dine el-Zinki groups said the prisoners were fighters from the Iraqi Nujaba Shiite militia, which has recently sent some 4,000 fighters to Syria to fight alongside government forces in Aleppo, a militia official told The Associated Press earlier this week. He spoke on condition of anonymity as he was not authorized to discuss the militia's strategy.
The Britain-based Syrian Observatory for Human Rights, which monitors the conflict through activists on the ground, reported that five presumed Iraqi militiamen had been taken prisoner by the rebels.
Syria's government depends on an array of foreign militias, elite Iranian fighters, as well as Russian military intelligence and air power to maintain its fight against the rebels, who also rely on foreign fighters.
The Observatory said clashes were underway Friday in Aleppo's southern Sheikh Saeed neighborhood, as well as along other fronts inside the city.
On Thursday, U.N. special envoy Staffan de Mistura urged fighters from the Fatah al-Sham Front, previously known as the Nusra Front, to evacuate to another part of the country to save the ancient city from complete destruction.
Russia's Foreign Minister Sergey Lavrov said Friday that Moscow backs the de Mistura's call, saying that Moscow is ready to ask Damascus to allow the militants to leave the city with their weapons "for the sake of saving Aleppo."
He added, however, that policies need to be developed to deal with other militants who choose to stay in Aleppo.
A Fatah al-Sham official in northern Syria told the AP via text message that the group's gunmen will not leave Aleppo, adding that they intend to stay to defend eastern parts of the city.
He said the group's fighters would only leave if the Shiite militias withdrew from Aleppo....
