Aug 28 (Reuters) - Colombia's international dollar bonds

rose across the curve on Thursday, a day after a group of global

banks announced an offer to repurchase Colombia's sovereign

bonds maturing from 2027 through 2061.

The 2027 issue gained 3 cents to bid at

102.76 cents on the dollar, while the 2061 added

2.87 cents to bid at 59.625.

The banks, including BNP Paribas, Citigroup Goldman Sachs

and JPMorgan and others launched the buyback in an offer

document circulated on Wednesday.
