Russia-backed Syrian forces make advances in IS-held Palmyra
Syrian government forces backed by heavy Russian air strikes have seized three areas inside Palmyra, a town which fell to the Islamic State group (IS) last May, state media reported.
Russian jets have carried out 40 air sorties near Palmyra in the past day, hitting 158 targets and killing more than 100 militants, Russia's defence ministry said.
Syrian troops and allied militiamen have taken up positions in the three neighbourhoods that are part of the modern town, which has famed Roman-era ruins, according to the UK-based Syrian Observatory for Human Rights.
Palmyra, affectionately known as the "bride of the desert," used to attract tens of thousands of tourists every year.
IS drove out government forces in a matter of days and later demolished some of the best-known monuments in the Unesco world heritage site.
The extremists believe ancient ruins promote idolatry.
The militants also demolished the town's infamous Tadmur prison, where thousands of Syrian government opponents were reported to have been tortured.
Retaking the town would be a major victory for Syrian president Bashar Assad's government, which has made steady gains in recent months against IS and other insurgents.
Syria's government has been assisted in large part by Russia's air campaign.
Earlier this month, Russian president Vladimir Putin ordered the surprise withdrawal of some Russian warplanes from Syria, but said that strikes against IS and the al-Qaida linked Nusra Front will continue.
Those groups have been excluded from a Russian- and US-brokered ceasefire that began on February 27, and has been largely honoured.
The battle for Palmyra, now entering its fourth week according to the Observatory, has not been easy.
Government forces lost at least 18 soldiers on Friday alone, including a major general, the Observatory and IS-affiliated media sites reported. The Observatory's figures indicate at least 56 soldiers have died in fighting this week.
Footage broadcast on Lebanese stations aligned with the Syrian government showed smoke rising over Palmyra's skyline, as tanks and helicopters fired at positions inside the town.
IS began evacuating civilians this week to other parts of its territories in Syria. No civilians remain in the town, a Palmyra resident who left earlier this week told reporters.
The fate of the archaeological site is not immediately clear. Activists citing sources among advancing government forces said the two sides were fighting over the area, while the Observatory said government forces had retaken the site. Syrian state media made no mention of the area.
The head of Syria's antiquities and museums authority described the condition of the remaining monuments - including the grand amphitheatre, the market place, public baths, and a long colonnade - as "excellent," with only minor damage, based on footage captured by a drone and broadcast on Russian television last week.
Maamoun Abdulkarim, head of the government's antiquities and museums department, said civil servants are prepared to assess the monuments and plan for their restoration "as soon as we are given the green light from the Syrian army".
"We will present our studies to Unesco so that Palmyra can once again be a world heritage site," said Mr Abdulkarim. "Palmyra is not just for Syrians, it is for the world."
If Syrian government forces retake Palmyra, they will be positioned to advance on the two largest Syrian cities held by IS, Deir Ezzor and Raqqa.
IS is on the back foot in Iraq and Syria, where forces on the ground have been backed by US-led air strikes against the extremists. The US-led international coalition estimates that the group has lost 40% of the territory it once held in Iraq and around 20% of its territory in Syria.
On Saturday, Turkish Air Force jets joined coalition forces in attacking IS in northern Iraq, hours after a Turkish soldier was killed at a military base in the region from rockets fired by the extremist militants.
Although Turkish jets have struck IS positions in Syria in the past, the attack marks Turkey's first aerial assault on the group in northern Iraq.
Ground forces in Iraq have been working to build on recent gains in Anbar province and preparing for an offensive on the northern city of Mosul, the largest city held by IS militants.
IS has responded to territorial losses by launching a series of large attacks targeting civilians.
The extremists claimed responsibility for a suicide bombing on Friday at a small football stadium in the Iraqi city of Iskanderiyah, 30 miles from the capital, Baghdad.
The attack killed 41 people and wounded 105.
Speaking at a press conference during an official visit to Iraq, UN Secretary General Ban Ki-Moon offered his condolences to the friends and families of those killed, adding that the "the international community stands with Iraqis in horror and outrage".
