Western intelligence
agencies have visited Damascus for talks on combating radical Islamist
groups, Syria's deputy foreign minister has told the BBC.
Faisal Mekdad said there was a schism between Western
security officials and politicians who are pressing President Bashar
al-Assad to step down.The growth of jihadist groups among rebels fighting President Assad has caused international concern.
Syrian government officials are due to attend peace talks in Geneva next week.
However, the main opposition alliance, the National Coalition, has still not decided whether or not to take part.
Correspondents say the growing disarray of the opposition is frustrating the West and bolstering the confidence of the Syrian government.
In a recent interview, Mr Mekdad told the BBC that many Western governments had finally understood that there was no alternative to the leadership of President Assad.

There is common concern between the West and Syria about the
threat posed by Islamist groups and the growing number of foreign
fighters from Europe.
What is not clear is how far the West is prepared to make common cause with a regime it still holds responsible for this brutal war.
Damascus has long maintained the West would eventually come round to accepting its narrative that this conflict is a battle against terrorism.
Western politicians still insist President Assad must eventually step down.
But informed sources say there have been meetings between Western and Syrian intelligence officials including Security Chief General Ali Mamluk.
It is hard to confirm the extent of contacts. Foreign nationals detained in Syria would have been on the agenda but there is said to have been broader discussion of security threats.
As this devastating war drags on, there is growing anxiety in many capitals over how to bring it to an end.
As one Western official put it: "This is a losing situation for absolutely everyone."

On the subject of whether Syria
was getting more requests from Western countries to have their diplomats
return to Damascus, he added: "Yes, there are many countries who are
approaching us.
"Of course some are waiting for Geneva, some are saying we
are exploring the possibilities, some are saying we want to co-operate
on security measures because those terrorists they are sending from
Western Europe into Turkey, into Syria, have become a real threat to
them."The UK Foreign Office told the BBC it does not comment on intelligence matters.
However, the BBC's chief international correspondent Lyse Doucet said informed sources had confirmed meetings between Western and Syrian intelligence officials.
On Tuesday, French President Francois Hollande told a press conference in Paris that 700 French nationals had joined the ranks of foreigners fighting in Syria.
The growing numbers of foreign Islamist fighters from Europe means there are common concerns, our correspondent says, but it is not clear how far the West is prepared to make common cause with a regime it holds responsible for the Syrian civil war.
An official from the National Coalition recently said the US and Britain had warned they would rethink their support if the group failed to join the peace talks.
Meanwhile, a donor conference to raise funds for the humanitarian crisis in Syria is taking place in Kuwait City on Wednesday.
Kuwait announced a pledge of $500m (£304m) towards efforts to combat the crisis, while the US promised $380m (£231m) in new contributions.
The UN says it is asking for $6.5bn (£4bn) over the coming year for Syria, its biggest ever funding request for a single crisis.
It is believed that more than nine million Syrians have been displaced by the uprising that began nearly three years ago.
Refugee camps outside Syria's borders are barely coping and reports from some besieged communities inside the country have warned of imminent starvation.
The UN says more than 100,000 people have died since the uprising began.
