BEIRUT: Air strikes blamed by Moscow and Damascus on the US-led coalition hit a Syrian army position in the east on Saturday, killing more than 60 soldiers, the Russian army said.
The situation in Syria is deteriorating, the Russian military said earlier, adding that the United States would be responsible if the current ceasefire breaks down.
“Warplanes from the international anti-jihadist coalition carried out four air strikes today against Syrian forces surrounded by the Islamic State group in the Deir Ezzor air base,” a Russian army statement said.
“Sixty-two Syrian soldiers were killed and a hundred others were injured in these strikes.”
The Russian military said two F-17 and two A-10 jets flew into Syrian airspace from neighbouring Iraq to carry out the strikes.
“Straight after the coalition’s strikes, IS militants launched an offensive,” said the statement, adding that “fierce fighting against the terrorists” ensued nearby.
“If these strikes were due to an error in the target coordinates, that would be a direct consequence of the US’ refusal to coordinate with Russia its fight against the terrorist groups in Syria,” it said.
The IS-affiliated Amaq news outlet said IS had seized the hill where the air strike took place.
Syrian state media also said coalition aircraft carried out the strike near Deir Ezzor airport and state news agency SANA spoke of casualties, without specifying a number.
Britain-based monitor the Syrian Observatory for Human Rights said at least 80 soldiers were killed, but could not specify who carried out the raids.
Syria’s army has been fighting off a fierce offensive by the militant Islamic State group on the Deir Ezzor military airbase since last year.
“This is a dangerous and bold attack against the Syrian state and army, and clear evidence that the United States and its allies support the terrorist group Daesh,” the army statement reported by the SANA official news agency said, referring to IS.
“The situation in Syria is worsening,” Russian General Vladimir Savchenko said in a televised briefing earlier.
“In the past 24 hours, the number of attacks have risen sharply,” with 55 attacks on government positions and civilians. He said 12 civilians had been killed.
Russian military officials lashed out at the United States in the strongest language yet over the ceasefire struck last week in Geneva, a last-ditch effort to stop the bloodshed in Syria.
The ceasefire started on Monday and has so far lasted five days.
“Russia is exerting all possible effort to restrain government troops from returning fire,” senior army general Viktor Poznikhir said during the televised briefing.
“If the American side does not take the necessary measures to carry out its obligations… a breakdown of the ceasefire will be on the United States.”
Russian President Vladimir Putin accused Syrian militants of using the ceasefire to regroup, as diplomatic tensions between Moscow and Washington simmered over a lack of humanitarian aid access.
In New York, the UN Security Council cancelled an urgent meeting that had been called to discuss whether to endorse the ceasefire, billed as the “last chance” to end the five-year war that has killed 300,000 people.
Friday’s closed-door consultations were scrapped after Moscow and Washington failed to agree over disclosing details of the ceasefire to the council.
Extending the truce
Putin, a key ally of Syrian President Bashar al-Assad, said Saturday he remained “positive” about the truce but lashed out at militants.
“We see attempts to regroup among these terrorists, to switch one label for another, one name for another and keep their military capacity,” he said in televised remarks.
Putin said Washington apparently “has the desire to keep the capabilities to fight the lawful government of President Assad,” calling it a “very dangerous path”.
Moscow said Friday that it was ready to prolong the truce by 72 hours, but there has been no formal announcement of an extension.
Implementing the truce has been complicated by the presence of militants — who are not covered by the ceasefire — and mainstream ‘rebels’ on some of the same frontlines.
A challenge for Washington is to persuade ‘moderate groups’ it backs to separate themselves from the former Al-Qaeda affiliate Fateh al-Sham Front, previously called Al-Nusra Front.
US Secretary of State John Kerry called his Russian counterpart Sergei Lavrov on Saturday and was urged to press the militants for safe passage guarantees, the Russian foreign ministry said.
A key plank of the truce deal was the delivery of aid to areas including Aleppo, where an estimated 250,000 people in militant-held areas of the city are living under government siege.
But 40 trucks carrying desperately needed food aid were still stuck on the border with Turkey on Saturday.
“Still no progress, but the UN is ready to move once we get the go ahead,” said David Swanson, a spokesman for the UN Office for the Coordination of Humanitarian Affairs.
Under the US-Russia deal, if the truce lasts seven days and humanitarian access is granted, Moscow and Washington are to work together to target jihadists including IS.
