The United States has suspended talks with Russia on trying to end the violence in Syria and accused Moscow of not living up to its commitments under a ceasefire agreement.
Both countries had been working to try to secure a ceasefire in Syria but the latest truce collapsed last month after several days of relative calm.
Following the deadly attacks on Aleppo, US Secretary of State John Kerry said the US was “on the verge” of ending talks on Syria with Russia.
The US government released a statement on Monday confirming the suspension of talks.
“The United States is suspending its participation in bilateral channels with Russia that were established to sustain the cessation of hostilities,” US State Department spokesperson John Kirby said in the statement.
“This is not a decision that was taken lightly.”
The announcement came hours after Russian President Vladimir Putin signed a decree to suspend an agreement with the US on disposing of weapons-grade plutonium, citing the US’ “unfriendly acts”.
Russia’s foreign ministry said it regretted the US decision to suspend Syria talks, saying Washington was trying to shift responsibility for the failure to halt violence onto Moscow.
“Washington simply did not fulfil the key condition of the agreement to improve the humanitarian condition around Aleppo,” ministry spokeswoman Maria Zakharova said.
“After failing to fulfil the agreements that they themselves worked out, they are trying to shift responsibility on to someone else”.
