Greece bought back 2.3 bln eur of its debt -sources

ATHENS, April 28 (Reuters) - Greece has bought back about 2.3 billion euros ($3.37 billion) of outstanding bonds and T-bills in the secondary market since the start of the year, government officials said on Thursday.

"Since the start of the year there have been debt buybacks totalling about 2.3 billion euros," one government official who declined to be named told Reuters.

Another official said this was part of treasury cash management operations and that debt buybacks during the same period last year were much smaller. (Reporting by Renee Maltezou and George Georgiopoulos)
