The eurozone's economy grew by a faster-than-expected 0.6% in the first three months of the year, according to official statistics, BBC News reports.
The growth rate in the 19-nation bloc doubled from the 0.3% rate recorded in the previous quarter, and was above analysts' expectations of 0.4%.
However, separate data from Eurostat also indicated that deflation had returned to the eurozone.
Inflation in the bloc fell to minus 0.2% in April, down from zero in March.
Other Eurostat figures showed the eurozone's unemployment rate fell to 10.2% in March, the lowest rate for four-and-a-half years.
