Russia has stationed troops between the Syrian army and Turkish forces in an attempt to prevent fresh clashes in northern Syria.

Moscow said its soldiers are now patrolling land outside the flashpoint city of Manbij, which was taken over by Syrian government forces on Tuesday, to prevent an anticipated Turkish attack.

Russia, which backs the Syrian government, said 'no one is interested' in fighting between Syrian government troops and Turkish forces and that Moscow 'is not going to allow it.'

But the Kremlin failed to prevent some skirmishes around the city, as the Turkish government said one of its soldiers was killed and eight more wounded in a mortar attack. Turkey said it returned fire and killed 15 'terrorists'.

Vladimir Putin has moved quickly to establish himself as power-broker in northern Syria, including striking a pact between the Kurds and Syrian government, after Donald Trump suddenly ordered US forces to withdraw.

Video also emerged of Russian forces occupying a former American base just outside of Manbij, which was hastily abandoned by US forces.

Russia moved into Manbij on Tuesday even as major fighting was underway in the city of Ras al-Ayn, with Kurdish forces launching a counter-attack after being reinforced by the Syrian army. Syrian army troops also reinforced positions in Ain Issa ahead of an expected counter-attack on Tel Abaid

A journalist travelling with Russian forces gave a tour of the base, which seemed to have been left virtually intact by the retreating Americans, saying: 'Let's have a look, how they lived, what there is here and where they went.'

Outside Manbij, Russian troops patrolled front lines between Turkish and Syrian army positions to keep them apart, Russia's Defense Ministry said.

'No one is interested' in fighting between Syrian government troops and Turkish forces, said Alexander Lavrentyev, Moscow's envoy for Syria. Russia 'is not going to allow it,' he told Russian state news agencies.

Kelly Craft, the US ambassador to the United Nations, told reporters Washington is 'deeply concerned' that Russian troops are patrolling between the two sides.

Russian Defense Minister Sergei Shoigu spoke to US Defense Secretary Mark Esper to discuss 'issues of mutual interest in the context of situation in Syria,' the Russian Defense Ministry said in a brief statement, without elaborating.

Russia has been a staunch ally of Assad for decades and entered the Syrian conflict in 2015, providing air power that eventually turned the tide of the war in his favor.

The Russian military has shipped weapons to Damascus, trained thousands of troops and put its advisers in key Syrian military units.

In the first week of the Turkish assault, at least 154 fighters from the Kurdish-led Syrian Democratic Forces have been killed, as well as 128 fighters from Turkish-backed Syrian factions , according to the Syrian Observatory for Human Rights, a monitor of the war.

It said at least 69 civilians have been killed in Syria. Turkey says six of its soldiers have died, as well as at least 20 Turkish civilians killed by Kurdish mortar fire across the border.

Despite the Syrian and Russian deployments, Turkey insisted it would capture Manbij. Asked on Sky News if Turkey's military was willing to fight Assad's army, Vice President Fuat Oktay said, 'We hope it's not going to happen, but again we are determined to get control over Manbij.'

President Erdogan has defended his attack on northern Syria, saying he acted after world leaders failed to stem the tide of refugees coming to Turkey - and told governments to either back him or begin admitting refugees themselves

The Turkish invasion entered its seventh day on Tuesday, with heavy fighting reported in the early hours around the border city of Ras al-Ayn.

Turkish forces opened fire with artillery and carried out at least one airstrike after a major Kurdish counter-attack overnight seized back parts of the border crossing point.

Erdogan spoke out to defended his attack on Syria saying he decided to act after world leaders failed to stem the tide of refugees arriving in his country.

He said the international community either needs to back his mission to open up a 'peace corridor' in Kurdish territory to resettle some 2million displaced people, or else begin accepting those people themselves.

Despite Erdogan's claims that his attack would help the refugee situation, Kurdish forces said some 275,000 people including 70,000 children have already been displaced by the fighting.

The Syrian Observatory for Human Rights said 'fortifications, tunnel networks and a continuous supply of reinforcements' had enabled the SDF to hold off Turkish efforts to take the town.

Erdogan spoke out after EU leaders agreed to restrict arms sales to Turkey, while America imposed heavy sanctions and called for a ceasefire.

The UK joined Italy, Germany, France, Finland, Sweden and the Netherlands on Wednesday by banning weapons sales to Turkey, though only of the kinds of weapons deemed most likely to be used in the conflict.

However, Erdogan showed no signs of slowing the assault down Tuesday, as he said the attack would not stop 'until our objectives have been achieved'.

'God willing, we will quickly secure the region stretching from Manbij to our border with Iraq and ensure that, in the first stage, one million, and then two million Syrian refugees return to their homes on their own free will,' he said.

Writing in the Wall Street Journal, the Turkish President also sought to allay fears that some 100,000 ISIS members currently held by Kurdish forces will escape during the onslaught.

'We will ensure that no ISIS (Islamic State) fighters leave northeastern Syria,' Erdogan wrote.

But he added that Western countries were hypocritical to worry that Turkey's operation against Kurdish militants risked a mass escape of jihadists.

'The same countries that lecture Turkey on the virtues of combating ISIS today, failed to stem the influx of foreign terrorist fighters in 2014 and 2015,' Erdogan wrote.

Turkish police also detained four mayors from a pro-Kurdish party in dawn raids, widening a crackdown since Ankara launched an incursion into northern Syria a week ago, state media said Tuesday.

The pro-Kurdish People's Democratic Party (HDP) mayors of the Kurdish-majority districts of Hakkari, Yuksekova, Ercis and Nusaybin, near Turkey's borders with Syria and Iraq, were held over terrorism links, the HDP and Anadolu news agency said, without elaborating.

President Tayyip Erdogan and his government accuse the HDP of being linked to the Kurdistan Workers Party (PKK) militant group, and thousands of its members have been prosecuted for the same reason, including its leaders.

The United States slapped sanctions on Turkey Monday as it demanded an end to the military operation, accusing its NATO partner of putting civilians at risk and allowing the release of extremists.

The alliance's Secretary General Jens Stoltenberg said on Tuesday that he was ' deeply concerned about the consequences' of the attack, including 'human suffering and stability in the wider region'.

Kurdish authorities claim the Turkish assault makes it difficult to maintain security at their detention centres.

They say 800 ISIS family members escaped a camp at Ain Issa on Sunday, and five jihadists broke out of another prison on Friday.

Turkey says Kurdish forces have deliberately set free detainees 'to fuel chaos in the area'. Some relatives of IS family members have made the same claim to AFP.

Ankara has vowed to take control of all detention centres in its operational area.

'We are prepared to cooperate with source countries and international organizations on the rehabilitation of foreign terrorist fighters' spouses and children,' Erdogan wrote in the Wall Street Journal editorial.

After earlier agreeing to hand control of regional security over to Turkey, Trump phoned Erdogan on Monday to demand an immediate end to Turkey's invasion of northern Syria.

Vice President Mike Pence said he was being dispatched 'as quickly as possible' to negotiate a ceasefire after Erdogan's forces stormed into northern Syria.

Pence said the president is 'very concerned about instability in the region' but denied that Trump had started it, saying he did not give Turkey the green light to launch the invasion when he announced a troop pullout.

'The United States of America simply is not going to tolerate Turkey's invasion in Syria any further.

'We are calling on Turkey to stand down, end the violence and come to the negotiating table,' Pence told reporters outside the White House.

He spoke just over two hours after Trump washed his hands publicly of the Kurds and invited 'Russia, China, or Napoleon Bonaparte' to save them.

Trump tweeted that he had put the fate of America's former Kurdish allies in the hands of Syrian dictator Bashar al-Assad, whose regime he called 'our enemy' in the same breath.

And he announced that his administration aims to punish Turkey's incursion into Syria by canceling a $100 billion trade agreement, hiking import tariffs on Turkish steel, and readying economic sanctions against anyone in Erdoğan's government who threatens 'peace, security, or stability' in Syria.

The Kurds were forced to sign a defence pact with the Russian-backed Syrian army Sunday in an effort to secure reinforcements for the fight against Turkey.

On Monday Bashar al-Assad's forces rolled into strategic positions along the new frontline, including the battlegrounds of Ras al-Ayn, Tel Abaid and Kobane.

Syrian army units also deployed to Manbij - even as Turkey prepared to attack the city - Al Tabqah and Raqqa.

It is not clear whether any of the troops have yet been involved directly in fighting, or whether they are simply supporting Kurdish fighters.

Any conflict between Assad's troops and Turkey would mark a turning point for the region, because Russia and Iran back the regime.

The two countries had previously allied with Turkey to create a peace plan for Syria.

It would also mark the first time the Kurds, America's closest ally in the country, had fought alongside Russian-backed troops.
