BEIRUT: Hopes for a quick political transition in war-ravaged Syria dimmed on Thursday as embattled President Bashar al-Assad threw cold water on an ambitious timetable agreed at international talks in Vienna.

At the same time, the US held firm to its calls for Assad’s departure, with President Barack Obama insisting on Thursday that the war could not end unless the Syrian leader steps down.

“I do not foresee a situation in which we can end the civil war in Syria while Assad remains in power,” Obama said on the sidelines of a trade summit in Manila.

Top diplomats from 17 countries met in Vienna on Saturday to discuss a way out of Syria’s nearly five-year conflict, which has left more than a quarter of a million people dead.

They produced a two-year timetable: a transitional government would be formed and a new constitution written within six months, to be followed by internationally monitored elections within 18 months after that.

But in a television interview with Italy’s Rai television, Assad said there could be no transition schedule for elections while swathes of Syria remained out of government control.

“This timetable starts after starting defeating terrorism. You cannot achieve anything politically while you have the terrorists taking over many areas in Syria,” he said.

“If we talk after that, one year and a half to two years is enough for any transition”. Damascus refers to all opponents — fighters and activists alike — as terrorists.Syria’s government has insisted that combatting “terrorist groups” including the self-styled Islamic State should come ahead of any political solution.

On Wednesday, IS’s English-language magazine said it had killed two hostages by printing graphic photos of two bodies that appeared to be Chinese hostage Fan Jinghui and Norwegian Ole-Johan Grimsgaard-Ofstad.

Assad also rejected the idea of UN observers monitoring elections, saying the world body had “lost all credibility”.

In comments to French magazine Valleures Actuelles, the embattled leader said Syria could only accept observers from countries that “were not partisan during the crisis”.

Meanwhile, Russian Foreign Minister Sergei Lavrov said would be ready to work with the Western coalition striking IS if its members respect Syria’s sovereignty.

Russia is “ready to develop with them such forms of coordination that of course would respect Syria’s sovereignty and the prerogatives of the Syrian leadership,” Lavrov told state-run Radio of Russia.

Despite holding diametrically opposed views on the fate of Assad, Russia and France are set to begin coordinating military and security efforts in the anti-IS fight.

The remarks by world leaders have rolled back hopes that a political solution was on the horizon.

On Tuesday, US Secretary of State John Kerry said Syria could be “weeks away” from a transition.

IS territory across eastern, central, and northern Syria is the target of a US-led air coalition as well as Russian strikes.

Air strikes on fuel trucks in IS’s de facto capital, Raqa, killed at least six civilians and wounded 20, the Syrian Observatory for Human Rights said.
