On March 13 the International Committee of the Red Cross (ICRC) warned that time was "running out" for those trapped by the Russian Army siege in Mariupol and that citizens there face a "a worst-case scenario" unless the warring parties reach an agreement to ensure their immediate safety and access to humanitarian aid. The ICRC said "a concrete, precise, actionable agreement" was needed without delay so civilians wanting to leave can reach safety, and life-saving aid can reach those who stay.[31]
