Reuters reports this additional information from Russian Foreign Ministry spokeswoman Maria Zakharova's press briefing this morning.
Zakharova said that there was still no agreement among global powers on the lists of Syrian opposition and terrorist groups.
"Unfortunately, the tempo of this work on the list of the opposition which could be presented in talks with Damascus, as well as on the list of terrorists, is not at the speed...which was presumed after the Vienna meetings," she said.
Zakharova was referring to an agreement made in November that Jordan would coordinate efforts to compile a common list of terrorist groups in Syria.
Russian Foreign Minister Sergei Lavrov reiterated this demand in his phone call on December 9 with U.S. Secretary of State John Kerry.
AFP's Ankara correspondent Fulya Ozerkan tweets that the first lot of German troops and aircraft has taken off for Turkey as part of a deployment in the anti-IS fight.
The U.S. commando force that President Barack Obama is dispatching to Iraq to conduct clandestine raids against the IS group does not fit neatly into a picture of the U.S. military strategy for defeating the militants, AP writes.
AP notes that usually, this sort of commando force works clandestinely and its existence would normally be classified.
"In this case the Pentagon lifted that veil to bolster its argument that the U.S. military strategy is building momentum at a time when its critics claim the Islamic State is winning," AP suggests.

Two Iraqis Detained In Finland Over IS Camp Speicher Mass Killing
Two Iraqi men have been detained in Finland on suspicion of terrorism-related murders in Iraq, Finnish media is reporting.
The two men were detained Tuesday, the head of Finland's National Bureau of Investigations, Jari Raty, told reporters at a press conference today. However they were not interviewed until today because of a shortage of interpreters.
The two men are suspected of 11 killings in Iraq in June 2014 as part of a mass killing carried out by IS at Camp Speicher near Tikrit, in which militants killed unarmed Iraqi Air Force cadets.
The suspects, both 23-year-old Iraqi men, arrived in Finland in September.
They allegedly shot Iraqi army cadets who had been tied up and made to lie on the ground.

U.S. Secretary of State John Kerry has said that progress has been made in Saudi-led talks in Riyadh to try to unite Syrian opposition groups ahead of talks with Syrian President Bashar al-Assad's government.
"The meeting in Saudi Arabia appears to be very constructive at this point ... but I think everybody is moving in the direction that they want to rapidly get to a political process," Kerry said on the sidelines of climate talks in Paris.
But a possible December 18 meeting in New York to try to advance the peace talks is "not locked in yet," Kerry added.
Five people, including a 15-year-old boy, have been charged today in Sydney, Australia over a terrorist plot targeting a government building.

Three other suspects aged 21, 22 and 23 were already in jail and were later charged with the same offense.
The plot linked to the arrest was not new but relating to an operation last December in which material about a planned attack on a government building was seized, police said.
