"Syria is determined to tackle terrorism and those who support it regionally and globally, and to find a political solution to the crisis," Assad told a Tunisian delegation on Thursday.

Assad also said that the "Syrians appreciate the positions of Tunisian people and are aware that some Tunisians came to fight in Syria, but they represent only themselves."

Tunisian Foreign Minister Othmane Jarandi estimated 10 days ago that some 800 Tunisians were fighting alongside the terrorist against the government in Syria.

On Saturday, Assad said that militants from 29 different countries are now fighting against the government in different parts of the country.

“Recent credible reports show that there are approximately 29 nationalities of foreign fighters engaged in terrorism activities within Syria’s borders,” he said.

As the Syrian army is struggling with a massive bloody insurgency throughout the country, US government has stepped up its pressures on the Syrian president Bashar al-Assad to leave his post and hand over the country to an opposition group which has turned to be a cover for terrorists such as al-Qaeda-linked al-Nusra Front.

The Syria crisis began in March 2011, and many people, including large numbers of soldiers and security personnel, have been killed in the violence.

The Syrian government says that the chaos is being orchestrated from outside the country, and there are reports that a very large number of the militants are foreign nationals.
