VIENNA, March 25 (Reuters) - Staff on duty at Chernobyl's Russian-held radioactive waste facilities have not been rotated in four days and Ukraine cannot say when that will change because of fighting in the town where many of them live, the U.N. nuclear watchdog said on Friday.
"Ukraine informed the International Atomic Energy Agency today that there had been no rotation of technical staff at (Chernobyl) since 21 March and it did not know when it might next take place," the IAEA said in a statement.
Staff now on duty replaced a shift that was there for more than three weeks.
