BEIRUT (Reuters) - Syrian government forces backed by heavy Russian air support drove Islamic State out of Palmyra on Sunday, inflicting what the army called a mortal blow to militants who seized the city last year and dynamited its ancient temples.
The loss of Palmyra represents one of the biggest setbacks for the ultra-hardline Islamist group since it declared a caliphate in 2014 across large parts of Syria and Iraq.
The army general command said that its forces took over the city with support from Russian and Syrian air strikes, opening up the huge expanse of desert leading east to the Islamic State strongholds of Raqqa and Deir al-Zor.
Palmyra would become “a launchpad to expand military operations” against the group in those two provinces, it said, promising to “tighten the noose on the terrorist group and cut supply routes ... ahead of their complete recapture”.
The Syrian Observatory for Human Rights said clashes continued on the eastern edge of Palmyra, around the prison and airport, but the bulk of the Islamic State force had withdrawn and retreated east, leaving the city under President Bashar al-Assad’s control.
Later the Observatory said six powerful explosions were heard in the city triggered by triple car bombings inside the city and its edges by the militant group. Three militants with suicide belts also blew themselves up inside the captured city, inflicting unspecified casualties among army forces and allied troops.
Syrian state-run television broadcast from inside the city, showing empty streets and badly damaged buildings.
It quoted a military source saying Syrian and Russian jets were targeting Islamic State fighters as they fled, hitting dozens of vehicles on the roads leading east from the city.
Russia’s intervention in September turned the tide of Syria’s five-year conflict in Assad’s favour. Despite its declared withdrawal of most military forces two weeks ago, Russian jets and helicopters carried out dozens of strikes daily over Palmyra as the army pushed into the city.
“This achievement represents a mortal blow to the terrorist organisation and lays the foundation for a great collapse in the morale of its mercenaries and the beginning of its defeat,” the army command statement said.
In a pointed message to the United States, which has led a separate Western and Arab coalition against Islamic State in Syria and Iraq since 2014, the military command said its gains showed that the army “and its friends” were the only force able to uproot terrorism.
In a phone call with Russian President Vladimir Putin, Assad said Russia’s air support had been essential in taking back Palmyra, and said the city would be rebuilt.
“Palmyra was demolished more than once through the centuries ... and we will restore it anew so it will be a treasure of cultural heritage for the world,” Syrian television quoted Assad as saying.
Observatory director Rami Abdulrahman said 400 Islamic State fighters died in the battle for Palmyra, which he described as the biggest single defeat for the group since it announced its cross-border caliphate nearly two years ago.
The loss of Palmyra comes three months after Islamic State fighters were driven out of the city of Ramadi in neighbouring Iraq, the first major victory for Iraq’s army since it collapsed in the face of an assault by the militants in June 2014.
Islamic State has lost ground elsewhere, including the Iraqi city of Tikrit and the Syrian town of al-Shadadi in February, as its enemies push it back and try to cut links between its two main power centres of Mosul in Iraq and Raqqa in Syria.
On Friday the United States said it believed it had killed several senior Islamic State militants, including Abd ar-Rahman al-Qaduli, described as the group’s top finance official and aide to its leader, Abu Bakr al-Baghdadi.
Islamic State and al Qaeda’s Syrian branch the Nusra Front are excluded from a month-long cessation of hostilities in Syria that has brought a relative lull in fighting between the government and rebels battling Assad in the west of the country.
The limited truce has allowed indirect peace talks to resume at the United Nations in Geneva, sponsored by Washington and Moscow. But progress has been slow, with the government and its opponents deeply divided over any political transition, particularly whether Assad must leave power.
The government delegation, which portrays the fight against terrorism as Syria’s overriding priority, will return to the talks next month bolstered by its battlefield gains.
“The liberation of the historic city of Palmyra today is an important achievement and another indication of the success of the strategy pursued by the Syrian army and its allies in the war against terrorism,” Syrian television quoted Assad as telling visiting French parliamentarians.
The Observatory said around 180 government soldiers and allied fighters were killed in the campaign to retake Palmyra, which is home to some of the most extensive ruins of the Roman empire.
Islamic State militants dynamited several monuments last year, and Syrian television broadcast footage from inside Palmyra museum on Sunday showing toppled and damaged statues, as well as several smashed display cases.
Syria’s antiquities chief said other ancient landmarks were still standing and pledged to restore the damaged monuments.
“Palmyra has been liberated. This is the end of the destruction in Palmyra,” Mamoun Abdelkarim told Reuters on Sunday. “How many times did we cry for Palmyra? How many times did we feel despair? But we did not lose hope.”
