REUTERS – The Russian air force and Syrian military are preparing a joint operation to take Aleppo from rebels, the Syrian prime minister was quoted saying on Sunday, and an opposition official said a cease-fire was on the verge of collapse.
With a UN envoy due in Damascus in a bid to advance struggling diplomatic efforts, the cessation of hostilities agreement brokered by Russia and the United States came under new strain as government and rebel forces fought near Aleppo.
The cease-fire came into effect in February with the aim of paving the way for a resumption of talks to end the five-year-long war. But it has been widely violated, with each side blaming the other for breaches. The fighting south of Aleppo marks the most significant challenge yet to the deal.
Diplomacy has meanwhile made little progress with no compromise over the future of President Bashar Assad, his position strengthened by Iranian and Russian military support.
A top Iranian official, in comments to Iran TV, rejected what he described as a U.S. request for Tehran's help to make Assad leave power, saying he should serve out his term and be allowed to run in a presidential election "as any Syrian."
Syrian Prime Minister Wael al-Halaki told a delegation of visiting Russian lawmakers of preparations to "liberate" Aleppo, Syria's biggest city and commercial hub before the conflict that erupted in 2011. Aleppo is divided into areas controlled separately by the government and opposition.
"We, together with our Russian partners, are preparing for an operation to liberate Aleppo and to block all illegal armed groups which have not joined or have broken the cease-fire deal," he was quoted as saying by TASS news agency.
Dmitry Sablin, a member of Russia's upper house of parliament and a member of the delegation, told RIA news agency "Russian aviation will help the Syrian army's ground offensive operation."
The deployment of the Russian air force to Syria last year helped tip the war Assad's way as it bombed rebels supported by his enemies, including Saudi Arabia, Turkey and the United States. President Vladimir Putin last month withdrew some of the Russian forces, but maintained an air base in Latakia, and kept up strikes on the Islamic State group.
Neither the Al-Qaida-linked Nusra Front or Islamic State are included in the partial cease-fire.
Rebels have reported the resumption of Russian airstrikes south of Aleppo, an important theater where Iranian forces and Lebanon's Hezbollah are fighting in support of the army and the Nusra Front is deployed in close proximity to rebels.
The Syrian Observatory for Human Rights said a total of 35 combatants had been killed on both sides in a 24 hour period in the area, where fighting has been raging for some 10 days.
"About to collapse"
A member of the main opposition council said the last 10 days had "witnessed a serious deterioration, to the point where the cease-fire is about to collapse."
Bassma Kodmani of the High Negotiations Committee also told Journal du Dimanche that a U.S.-Russian cease-fire monitoring mission was "powerless."
Rami Abdulrahman, director of the Syrian Observatory for Human Rights, said "in Aleppo there is a real collapse of the truce."
The army says groups that had agreed to the cessation of hostilities had taken part in Nusra Front attacks on government-held positions south of Aleppo. Free Syrian Army groups meanwhile blame the fighting on government violations.
"The airstrikes are now roughly back to what they were," said Mohamed Rasheed, head of the media office with the Jaysh al-Nasr rebel group. A Syrian military source said: "The battles are raging because armed groups that were part of the (truce) joined Nusra in the attack."
The observatory also reported fighting on Sunday between government and rebel forces near the opposition-held town of Douma outside Damascus, and said government helicopters had dropped barrel bombs on rebel-held areas north of Homs.
Barrel bombs are oil drums filled with explosives. While the government denies dropping them, their use has been widely recorded, including by a UN Commission of Inquiry on Syria.
Iran rejects U.S. "precondition"
UN envoy Staffan de Mistura is due to arrive in Damascus on Sunday evening, and is expected to meet Syrian officials on Monday. He said last week he would go to Damascus and Tehran to sound out their position on a political transition before beginning a new round of peace talks on Wednesday.
De Mistura has said the next round of talks needs to "be quite concrete in the direction of a political process leading to a real beginning of a political transition."
Ali Akbar Velayati, Iran's Supreme Leader Ayatollah Ali Khamenei's top adviser on international affairs, said U.S. Secretary of State John Kerry had asked "Iran to help so that Assad leaves. "We should ask them: "What does this have to do with you? Shouldn't the Syrian people decide?'"
"From Iran's point of view Bashar Assad and his government should remain as a legal government and legal president until the end of his term. And Bashar Assad shall be able to take part in a presidential election as any Syrian citizen. And their precondition that Bashar Assad should go is a red line for us."
In a sign of Assad's confidence, the Syrian government plans to hold parliamentary elections on Wednesday. Salim al-Muslat, opposition spokesman, said the vote was illegitimate.
"I don't know how they can really announce an election in Syria. In Idlib or in Aleppo or in Deir al-Zor or in Homs, can people go there and vote?" he said.
