Syrian President Bashar al-Assad, who has been conducting a nearly four-year bloody crackdown on his own people, said US plans to train vetted rebels to fight Islamic State (ISIS) terrorists were "illusory" as they would eventually defect to the jihadists, in an interview published Monday.

The Syrian leader also questioned talks to be held in Moscow this week, telling Foreign Affairs magazine that his government would attend but was not convinced the opposition figures taking part represented Syrians on the ground, reports AFP.

Washington has backed the Syrian opposition since early in the uprising and has unveiled plans to train more than 5,000 vetted rebels in Qatar, Saudi Arabia and Turkey to fight ISIS.

Assad said the planned US-trained force would be "illegal" and would be treated like any other rebel group. "They are going to be fought like any other illegal militia fighting against the Syrian army," he said.

"Bringing 5,000 (fighters) from the outside will make most of them defect and join ISIS and other groups. The idea itself... is illusory," he said.

The Pentagon has itself acknowledged that identifying and vetting potential rebel recruits for training is a difficult task that cannot be accomplished quickly without significant risks.

Assad questioned the seriousness of the US-led campaign against the jihadists, claiming "what we've seen so far is just, let's say, window-dressing, nothing real. Did the United States put any pressure on Turkey to stop the support of Al-Qaeda? They didn't."

He was referring to his government's longstanding accusations that Ankara has backed rebel groups including ISIS's jihadist rivals in the Al-Qaeda affiliate Al-Nusra Front.

Meanwhile Assad's troops have been responsible for more atrocities than ISIS during the conflict that has already claimed over 200,000 lives according to a UN report last September, despite the media preoccupation with ISIS in recent months.

Political solution from Russia?

Assad said the nearly four-year-old conflict could only be ended with a political solution, but cast doubt on the value of talks being organized this week by his key ally Russia.

The dialogue, which was due to open later on Monday and run through Thursday, was intended to bring together government and opposition representatives, but the main exiled opposition bloc, the National Coalition, is boycotting.

"Any talks should be held in a neutral country and overseen by the United Nations," a source in the coalition said, referring to Russia's status as a key Assad ally. Five members of the National Coalition will attend in a personal capacity along with members of opposition groups tolerated by the Damascus authorities.

Assad said his government would attend, but asked: "Who do you negotiate with? We have institutions, we have an army and we have influence."

"The people we are going to negotiate with, who do they represent?" he said, dismissing the strong opposition movement that has been rebelling to his autocratic rule for many years.

His government has long argued that the exiled opposition does not represent people inside Syria, accusing it of being "puppets" of its main foreign backers, Qatar, Saudi Arabia, Turkey and the United States.
