The design criteria for jet engines state they must be able to contain fan AND/OR turbine disc failiures, think united DC10, these pictures look remarkably like a turbine disc fail. If any fan blades are damaged or missing its usually after the initial turbine fail and a result of shaft imbalance , a bad disc fail will usually result in the translating sleeve damaged or missing.
Will be interesting to see the official findings on why such a new , low hours engine failed so spectacularly.
