Greece raised 1.3 billion euros ($1.84 billion) in a sale of six-month treasury bills on Tuesday, paying a slightly lower return of 4.8 percent to investors, the debt management agency (PDMA) said. \"The total bids reached 3.020 billion euros and the amount finally accepted was 1.3 billion euros,\" the debt management agency said. The issue, which had an original target of one billion euros, comes as top European officials are struggling to overcome differences in applying a new bailout of debt-plagued Greece agreed in July.
