Russia will not send a representative to a meeting of the "Friends of Syria" in Paris on Friday, French Foreign Minister Laurent Fabius said.
"Russia was invited. It let it be known that it did not want to participate, which was not a surprise," Fabius said after a meeting with his German counterpart Guido Westerwelle.
The Turkish military has said it scrambled F-16 fighter jets on Monday for a third consecutive day after Syrian helicopters were seen near the Turkish border. Turkey said it first launched a similar military action on Saturday.
The Turkish military added that a total of six jets, four from a base in Incirlik in the south and two from Batman in eastern Turkey were scrambled.
Reuters reports that Russia's foreign minister Sergei Lavrov has revealed Syrian opposition leaders are to arrive in Moscow next week for meetings about the crisis.
Turkey's Deputy Prime Minister Bekir Bozdag has said Syrian President Bashar al-Assad's comments over the downing of a Turkish jet last month were trying to connect with public opinion.
He also refuted suggestions that the aircraft which shot down a Turkish plane was flying in air space often used by Israel.
The Human Rights Watch report documents more than 20 distinct torture methods used by the security and intelligence services.
A 31-year-old detainee who was held in Idlib governorate in June described to Human Rights Watch how the intelligence agencies tortured him in the Idlib Central Prison.
Mr Hague said the UK would work with EU partners to impose sanctions on those responsible to help bring an end to the violence.
The report, Torture Archipelago: Arbitrary Arrests, Torture and Enforced Disappearances in Syria's Underground Prisons since March 2011, includes maps locating detention centres, video accounts from former detainees and sketches of torture techniques.
Almost all the former detainees interviewed by Human Rights Watch said they had been subjected to torture or witnessed the torture of others during their detention.
Assad reportedly told Turkey's Cumhuriyet newspaper in an interview published today:
Foreign Secretary William Hague said a report by Human Rights Watch that identified torture and atrocities in Syria sounded a clear warning that there was "no hiding place" for those responsible for such crimes.
The rights organisation has carried out more than 200 interviews since the beginning of anti-government demonstrations in the country in March last year.
Accounts from former detainees and defectors have identified the locations, agencies responsible, torture methods used and, in many cases, the commanders in charge of 27 detention facilities run by Syrian intelligence agencies.
Human Rights Watch said the systematic patterns of ill-treatment and torture it had documented clearly pointed to a "state policy of torture and ill-treatment", which constituted "a crime against humanity".
Syrian president Bashar al-Assad has said in an interview with a Turkish newspaper that he wishes Syrian forces did not shoot down a Turkish jet last month.
Reuters reports Assad stated he will not allow tensions between Syria and Turkey to turn into open combat.
