"The departure of the cargo ship Razoni flying the flag of Sierra Leone and loaded with maize will leave the port of Odesa bound for Lebanon at 8:30 a.m. (0530 GMT)," the ministry said in a statement, adding other convoys would follow along the maritime corridors because the "procedures are complete."
