France's foreign ministry said Friday that humanitarian corridors allowing civilians to escape Syria's besieged east Aleppo were not a "credible solution".
"International humanitarian law demands that aid must be sent urgently. The residents of Aleppo must be able to stay home in security and receive all the aid they need," said ministry spokesman Romain Nadal.
"In this context, humanitarian corridors, which require residents of Aleppo to leave the city, do not represent a credible response to the situation."
Pro-regime forces have surrounded Aleppo's eastern districts since July 17, leaving an estimated 250,000 trapped without reliable access to food or medical aid.
Russia, a key ally of President Bashar al-Assad, on Thursday announced the opening of humanitarian passages for civilians and surrendering fighters seeking to exit the city's rebel-held eastern neighbourhoods.
