Syrian deputy foreign minister "Faisal al-Mekdad" said in remarks broadcast that the intelligence services of some Western countries have visited Damascus to discuss security cooperation with the Syrian government.
Al-Mekdad said "I will not specify which countries, but many of them have visited Damascus, yes".
Asked about the report, U.S Secretary of State "John Kerry" indicated he was not aware of such contacts.
"I don't know anything about that. Certainly not under my auspices" has there been any contact of that kind, he told reporters in Kuwait, where he is on a visit.
Mekdad said that the contacts appeared to show a rift between the political and security authorities in some countries.
He stressed "frankly speaking the spirit has changed", adding "when these countries ask us for security cooperation, then it seems to me there is a schism between the political and security leaderships".
Western powers have supported the opposition with rhetoric but have backed away from material aid as Al-Qaeda-linked groups take advantage of a power vacuum in rebel-held regions.
Western countries are worried about the presence in militant ranks of foreign Islamist militants who have travelled to Syria to join a near three-year-old struggle .
Asked if he was confirming that British intelligence had been in contact with Syria, he declined a direct reply.
"I am saying that many of these countries have contacted us to coordinate security measures", he added.
