BEIRUT — Russia warned the United States Saturday against carrying out any attacks on Syrian government forces, saying it would have repercussions across the Middle East as government forces captured a hill on the edge of the northern city of Aleppo under the cover of airstrikes.
Russian news agencies quoted Foreign Ministry spokeswoman Maria Zakharova as saying that a U.S. intervention against the Syrian army "will lead to terrible, tectonic consequences not only on the territory of this country but also in the region on the whole."
She said regime change in Syria would create a vacuum that would be "quickly filled" by "terrorists of all stripes."
U.S.-Russian tensions over Syria have escalated since the breakdown of a cease-fire last month, with each side blaming the other for its failure. Syrian government forces backed by Russian warplanes have launched a major onslaught on rebel-held parts of the northern city of Aleppo.
Syrian troops pushed ahead in their offensive in Aleppo on Saturday capturing the strategic Um al-Shuqeef hill near the Palestinian refugee camp of Handarat that government forces captured from rebels earlier this week, according to state TV. The hill is on the northern edge of the Aleppo, Syria's largest city and former commercial center.
The powerful ultraconservative Ahrar al-Sham militant group said rebels regained control Saturday of several positions they lost in Aleppo in the Bustan al-Basha neighborhood.
Airstrikes on Aleppo struck a clinic in the eastern rebel-held neighborhood of Sakhour putting it out of service, according to the Britain-based Syrian Observatory for Human Rights and the Local Coordination Committees. They said one person was killed in the airstrike.
Opposition activists have blamed the President Bashar Assad's forces and Russia for airstrikes that hit Civil Defense units and clinics in the city where eastern rebel-held neighborhoods are besieged by government forces and pro-government militiamen.
Sweden's Foreign Minister Margot Wallstrom criticized attacks on civilian targets writing on her Twitter account: "Unacceptable to bomb civilians, children and hospitals in #Aleppo. No humanity. Assad & Russia moving further away from peace."
In the eastern province of Deir el-Zour, warplanes of the U.S.-led coalition destroyed several bridges on the Euphrates river, according to Syrian state news agency SANA and Deir el-Zour 24, an activist media collective. The province is a stronghold of the Islamic State group.
SANA said that among the bridges destroyed was the Tarif Bridge that links the eastern city of Deir el-Zour with the northern Syrian city of Raqqa, the extremists' de-facto capital.
