Russian President Vladimir Putin has pledged to continue political, economic and military support Syria as he called on all Middle East nations to join forces against ISIS.

More than 220,000 people have died since the Syrian conflict began in 2011, with ISIS factions now controlling parts of the Syrian capital and large parts of the city's suburbs.

Putin called on all nations to 'pool their efforts together' to fight Islamic militants, regardless of their relations with Syria, during a visit by Syrian officials.

The Russian leader told the Syrian envoy that Russia's 'policy to support Syria, the Syrian leadership and the Syrian people remains unchanged.'

Syrian foreign minister Walid al-Moallem held talks with Russian counterpart Sergey Lavrov on Monday before heading to the Kremlin to meet with Putin.

'I got a promise of aid to Syria - politically, economically and militarily,' al-Moualem said at a televised news conference after meeting the Russian leader.

Insurgent groups have made gains against government forces in northwest, central and southern Syria in the past two months but Damascus has voiced confidence that it can hold on to important territory with the help of its allies.

Two days ago, Kurdish fighters announced they had retaken the key Syrian border town of Kobani just one day after it was seized by 'lunatic' Isis militants who murdered more than 200 civilians.

The fighters declared they had killed more than 60 Isis militants as they regained control of the town - just two days after the hardline group attacked it with suicide bombers and machine guns.

But Syria has relied on help from its allies - Russia, Iran and Lebanese Shi'ite group Hezbollah - in the four-year conflict, which is now under some of the heaviest pressure since the start of the civil war.
