A convoy of 45 Red Cross buses will head for the besieged Ukrainian port city of Mariupol on Friday, hoping to evacuate as many citizens as possible while bringing fresh supplies and food for those still trapped, the BBC reports. “We confirm the convoy is moving from Dnipro to Zapporizhzhia, and we desperately hope it can enter Mariupol tomorrow. For logistics and security reasons, we’ll be ready to lead the safe passage operation tomorrow, Friday, provided all the parties agree to the exact terms, including the route, the start time, and the duration. It’s desperately important that this operation takes place. The lives of tens of thousands of people in Mariupol depend on it,” said a spokesperson for the International Committee of the Red Cross.
