5 dead as Russian military helicopter downed in Syria

A Russian military helicopter was shot down over Syria on Monday, killing all five people on board in the single deadliest incident for Moscow since it intervened in the war.

The attack came as Syrian rebel shelling left 28 civilians dead and dozens wounded in government-controlled southwestern districts of the battleground city of Aleppo.

Russia's defence ministry announced the downing of the helicopter, which it said was carrying three crew and two officers.

"A Russian Mi-8 military transport helicopter was shot down from the ground after delivering humanitarian aid to Aleppo," the defence ministry said in a statement quoted by Russian news agencies.

The Kremlin said all five people on board were assumed dead.

"As far as we know from the information we've had from the defence ministry, those in the helicopter died, they died heroically, because they were trying to move the aircraft away to minimise victims on the ground," Kremlin spokesman Dmitry Peskov told journalists.

Lieutenant General Sergei Rudskoy called the downing a "terrorist act" and said the defence ministry was still trying to confirm the fate of the Russian servicemen "through all possible channels".

It was not immediately clear who was responsible.

The incident was the deadliest single attack on Russian forces in Syria since Moscow began its intervention in support of President Bashar al-Assad's government last September.

It brought the total number of members of the Russian forces killed in Syria to 18.

The Syrian Observatory for Human Rights, a Britain-based monitor, said the helicopter had come down along the administrative border between Idlib province in the northwest and neighbouring Aleppo.

Idlib is held almost entirely by a powerful coalition of Islamist and jihadist forces including the former Al-Nusra Front, now known as the Fateh al-Sham Front after renouncing its status as Al-Qaeda's Syrian affiliate.

In neighbouring Aleppo province, shells fired by Syrian rebel groups killed at least 28 civilians -- including six children and eight women -- over the last 24 hours, the Britain-based Observatory said.

Syrian state news agency SANA said that since Sunday, 20 civilians were killed and dozens wounded in shelling, rocket fire and sniper attacks on government-held neighbourhoods.

The city's southern edges have been ravaged by fighting in recent days as the Fateh al-Sham Front and allied Islamist rebel groups seek to ease a government siege of the rebel-held east of the city.

The Observatory said the rebels had advanced overnight south and southwest of Aleppo, but reported ongoing fighting, as well as government air strikes on the battlefield and rebel-held eastern neighbourhoods.

Once Syria's economic powerhouse, Aleppo city has been roughly divided between government control in the west and rebel control in the east since mid-2012.

In recent weeks, government forces have encircled the east, cutting the sole supply route in and raising fears of a humanitarian crisis for the estimated 250,000 people now under siege there.

The primary goal of the rebel assault is to seize the Ramussa neighbourhood on the city's southern outskirts.

"The road that runs through Ramussa is the main supply route for regime forces going to the areas they control in western Aleppo," said Observatory head Rami Abdel Rahman.

It is also used by civilians to enter and leave government-controlled districts of Aleppo. Taking a detour from the north would be too dangerous, he added.

Islamist group Ahrar al-Sham said on Twitter it was involved in fierce clashes near Ramussa and advancing towards the route.

- 'Humanitarian corridors' -

SANA said people were using the route as usual, but residents of western Aleppo expressed fears that the assault could cut them off.

"If the militants break the siege, they will besiege us and cut the Khanasser route, which is the only artery we have," said Hossam Qassab, a 32-year-old pharmacist.

A Syrian security source acknowledged the assault but said government forces had repelled it.

The encirclement of eastern Aleppo has raised fears of starvation for remaining residents, who have reported food shortages and spiralling prices since the government siege began on July 17.

Last week, Moscow announced the opening of "humanitarian corridors" from the east into government territory for civilians and surrendering rebels.

On Saturday, Moscow and Syrian official media reported dozens of civilians had fled via these corridors, but residents and rebels on the ground dismissed the reports as "lies".

Elsewhere in Aleppo province, the Syrian Democratic Forces, a US-backed Kurdish-Arab alliance, advanced inside the Islamic State group bastion of Manbij on Monday, the Observatory reported.

The SDF hold approximately 40 percent of the town, and are fighting to take it with support from the US-led coalition against IS.
