U.S. President Barack Obama and German Chancellor Angela Merkel had a phone call on September 29. During the conversation both leaders of the USA and Germany condemned "barbarous" Russia and Syrian air strikes on Aleppo, emphasizing that Russia "bears special responsibility for ending the fighting in Syria and granting the UN humanitarian access to besieged and hard-to-reach areas in Syria".
Early U.S. Secretary of State John Kerry said Washington claimed the U.S. is ready to suspend negotiations with Russia on a peacetalks involving cease-fire agreement in Syria after cruel bombardment of the city of Aleppo by Russian and Syrian warplanes and advancing of Assad soldiers.
The Kremlin dismissed U.S. threats to suspend cooperation with Moscow in Syria and said Russian forces would continue to support a government offensive on rebel-held neighborhoods of Aleppo.
The White House underlined that the city is "populated with hundreds of thousands of civilians, half of whom are children". In addition two of the largest hospitals in the city's east were bombed earlier in the day in what United Nations Secretary-General Ban Ki-moon described as a "war crime."
In the telephone conversation with Russian Foreign Minister Sergei Lavrov on September 29 the U.S. State Department Kerry noted the "fragility" of the situation in Syria.
Washington regards the situation in Syria as "very serious" and is expecting more "significant steps" to be taken by Moscow in order to evade the potential suspending of its arrangement on Syria and execute liabilities undertaken.
"The Russian blitzkrieg on Aleppo Is a direct challenge to Washington" remarks The Nation. The Syrian cease-fire was already in tatters. But the new offensive is also early preparation for a hawkish Clinton presidency.
