International peace envoy Lakhdar Brahimi warned after meeting President Bashar al-Assad on Saturday that the worsening conflict in Syria poses a threat to the region and the world at large.
"The crisis is dangerous and getting worse, and it is a threat to the Syrian people, the region and the world," said the newly-appointed Brahimi, who took over as envoy earlier this month from former UN chief Kofi Annan.
Assad, quoted by state television, said that dialogue between Syrians held the key to a solution and called for foreign countries to stop supplying arms to his foes.
"The real problem in Syria is that of combining politics with the work being done on the ground," he said. "The political work continues, in particular by calling for dialogue between Syrians based on the aspirations of all Syrians.
"The success of political action is dependent on putting pressure on the countries that finance and train the terrorists, and which bring weapons into Syria, until they stop doing so," he said.
Eighteen months into Syria's deadly conflict and without an end in sight, Assad said his government would "cooperate with all sincere efforts to solve the crisis, so long as the efforts are neutral and independent."
Brahimi, a 78-year-old veteran Algerian troubleshooter, has also met with Foreign Minister Walid Muallem and members of the officially tolerated opposition since he arrived in the Syrian capital on Thursday.
The envoy called for a united effort. "There is need for all parties to unite their efforts to find a solution for the crisis, given Syria's strategic importance... and the crisis's influence over the whole region," he said.
"The solution can only come from the Syrian people," stressed Brahimi, who was to hold talks later on Saturday with Arab ambassadors and a European Union delegation.
Brahimi already warned on arrival that the conflict is "getting worse," as underlined by the daily bloodshed.
The Syrian Observatory for Human Rights, which gathers information from a network of activists on the ground, said 132 people were killed in violence on Friday, including 100 civilians, 18 of whom died in the capital.
Brahimi held talks on Friday with Syrian opposition figures who said he was bringing "new ideas" to the peace effort, as blasts rocked Damascus and regime air strikes targeted rebel areas in the northern city of Aleppo.
He met with opposition groups tolerated by Assad's regime such as the National Coordination Committee for Democratic Change, which groups Arab nationalists, Kurds and socialists.
The group said it was sending a delegation on Saturday to China, a key Damascus ally, to urge Beijing to "put pressure on the regime to stop the violence, free detainees and allow peaceful protests."
Brahimi is on his first Damascus visit since his appointment to replace Annan who quit the post after a hard-sought peace deal he brokered became a dead letter.
