Russia blames US for intensified conflicts in Syria
The US failed to help separate terrorists from the so-called moderate opposition, said Russia
 "Russia blames US for intensified conflicts in Syria")
Conflicts in Syria have intensified over the week despite the Russia-US truce accord which started on Monday, as militants continued targeting Syrian government troops, the Russian Defence Ministry said on Sunday.
"Only the Syrian government forces have observed the cessation of hostilities over the past six days since it came into effect... while militants attacks against the Syrian army are on the rise," the ministry's spokesman Maj Gen Igor Konashenkov said.
The US failed to help separate terrorists from the so-called moderate opposition, and neither did it exert necessary pressure on them, Konashenkov added.
The situation is especially grave in the northern city of Aleppo, where movements of armoured vehicles and cars have been recorded in the eastern part of the besieged city and its suburbs, said the spokesman.
On September 10, Russian Foreign Minister Sergey Lavrov and US Secretary of State John Kerry announced a nationwide cease-fire in Syria, which demands all warring sides stop attacks and airstrikes, and allow access to besieged areas, including Aleppo.
The cease-fire deal is now threatened with a recent escalation between Moscow and Washington, after the US-led airstrikes killed 90 Syrian servicemen in the eastern province of Deir al-Zour on Saturday.
The Russian Foreign Ministry said earlier on Sunday that the move would "put the implementation of the agreement in danger".
