Recently al-Assad finally spoke about the refugee crisis and pointed the blame at Europe for "supporting terrorists."

RT was also present at the Russian press interaction, and got the president's responses. Assad suggested that Europe was "not dealing with the cause"

"It is not about that Europe didn't accept them or embrace them as refugees, it's not about dealing with the cause. If you are worried about them, stop supporting terrorists. That's what we think regarding the crisis. This is the core of the whole issue of refugees."

The president conceded to the fact that all the Syrians were looking for was security and safety, and that political forces "should unite around what the Syrian people want." 

"If we ask any Syrian today about what they want, the first thing they would say - 'We want security and safety for every person and every family,'" he said.
