"The UN has a credible plan for meeting humanitarian needs in eastern Aleppo which opposition armed groups agreed to last week, all that is needed is a decision by the Assad regime to allow this aid in," the spokesperson said.
The situation in Aleppo has been seriously deteriorating over the recent months. Thousands of civilians are trapped in the terrorist-besieged eastern parts of Aleppo with no access to food or water. There have been several attempts to establish a ceasefire, however the bids have failed.
On Tuesday, the Russian Defense Ministry said that the Syrian government forces had cleared almost half of eastern Aleppo from militant strongholds, liberating tens of thousands local residents.
The Syrian civil war is ongoing since March 2011, with different countries, regional powers and terrorist organizations such as Daesh and Jabhat Fatah al Sham (previously known as al-Nusra Front) involved in the conflict.
