"The Syrian governmant troops have stopped firing and begun to withdraw their tanks, IFV and artillery to a set distance to create a demilitarized zone. The Russian Aerospace Force and the Syrian Air Force have stopped airstrikes on areas where opposition units may be located," Lt. Gen. Viktor Poznikhir, first deputy chief of the General Staff's Main Operational Department, told reporters.
He added that the Russian Defense Ministry "has no information related to similar actions by opposition groups controlled by the US."
The first deputy chief of the General Staff's Main Operational Department also said that withdrawal from Castello road in Aleppo may be halted if militants fail to do it simultaneously with the Syrian army.
Moreover, the Russian General Staff voiced concern over a steady increase in ceasefire violations in Syria by opposition militants caused by Washington's failure to separate 'moderate opposition' from al-Nusra Front terrorists.
"We are concerned about a steady increase in ceasefire violations by opposition armed groups," Lt. Gen. Viktor Poznikhir, first deputy chief of the General Staff's Main Operational Department, told reporters.
The general linked the increase in violations with the failure by the US side to separate US-backed 'moderate opposition' from the Jabhat Fatah Al-Sham terrorist group, formerly known as al-Nusra Front.
