Russia: US, UK remarks unacceptable

A diplomatic solution appears unlikely as violence has escalated since a truce collapsed

Moscow on Monday slammed the United States and Britain for accusing Russia of "barbarism" and war crimes in Syria as Russian and Syrian warplanes continued to bomb rebel-held areas of Aleppo.

"We note the overall unacceptable tone and rhetoric of the representatives of the United Kingdom and the US, which can damage and harm our relations," Kremlin spokesman Dmitry Peskov told reporters.
