Russia assumed to be behind decision to abort evacuations, says WHO

Elizabeth Hoff, the World Health Organisation's representative in Syria, speaking from west Aleppo, told a news briefing in Geneva: "I assume the message (to abort the operation) came from the Russians who are monitoring the area." Her team of nine staff in east Aleppo had no contact with Syrian authorities at the Ramouseh transit site. 

The evacuation of wounded and civilians from eastern enclaves of Aleppo was aborted on Friday, and aid agencies and vehicles told to leave the area without explanation.
