WASHINGTON (Web Desk) – The US has suspended has suspended bilateral contacts with Russia over Syria, the State Department said.

That occurred after last week’s threat by Secretary of State John Kerry to suspend contacts amid new attacks on the city of Aleppo.

According to a statement, that Russia had not lived up to the conditions of an accord last month to reinstate the cease-fire and ensure sustained deliveries of humanitarian help to besieged cities on Monday, Indian Express reported.

As part of the suspension, the US is withdrawing personnel that it had dispatched to take part in the creation of a joint US-Russia center.

That center was to have coordinated military cooperation and intelligence if the cease-fire had taken grip.

The suspension will not affect communications between the two countries aimed at de-conflicting counter-terrorism operations in Syria.
