Aleppo - Several thousand people, including a seven-year-old girl who tweeted from inside Aleppo, were evacuated on Monday, raising hope for many others still stranded as Russia eased its objections to sending UN observers to oversee the evacuations.Bana Alabed, who has been tweeting about life in the destroyed city of Aleppo, has over 300 000 followers on Twitter.The account, which she shares with her mother, went silent a few weeks ago as the Syrian regime attacked eastern Aleppo.The tweets had in recent weeks become more desperate.The President of Syrian American Medical Society has since tweeted a picture with Bana, saying she and many other children were safe..@AlabedBana and many children arrived to #Aleppo countryside. @sams_usa @UOSSM and partners arr coordinating the response plan there. pic.twitter.com/k3iAohYbFY— Ahmad Tarakji, MD (@tarakjiahmad) December 19, 2016 This morning @AlabedBana was also rescued from #Aleppo with her family.

A medic said the latest evacuees from Aleppo were in a "terrible state" after their departure was delayed for hours in temperatures well below freezing, compounding their plight from months of siege and bombardment by the army.Ahmad al-Dbis, who heads a team of doctors and volunteers coordinating evacuations, saw dozens of buses arrive at the staging ground west of Aleppo.He said they were in "a very bad state after waiting for more than 16 hours" at a regime checkpoint without being allowed off the buses. "They hadn't eaten, they had nothing to drink, the children had caught colds, they were not even able to go to the toilet," Dbis said.
