MOSCOW, October 19. /TASS/. Head of the State Duma Committee for International Affairs Leonid Slutsky presumed on Wednesday that the United States specially wants to preserve Jabhat al-Nusra terrorist organization to overthrow Syrian President Bashar Assad.

"With regard to very strange calls to us against bombing Jabhat al-Nusra because, as they say, representatives of the moderate opposition may suffer, a systemic impression is created that the United States wants to keep Jabhat al-Nusra to use it in the imminent future to implement the obsessive idea and overthrow Assad," the lawmaker said.

According to Slutsky, "Russia has been fed with promises since February" that the United States will shortly separate al-Nusra terrorist organization from the so-called moderate opposition in Aleppo.

However, this is not taking place, the parliamentarian said.

"The Castello Road is not being unblocked and when the government troops recede by 1.5 km at our request, the oppositionists do not withdraw. The United States claims that it allegedly has no influence on them," the lawmaker said.
