Industrial output in the eurozone fell by more than expected in June as the manufacture of capital and durable goods slowed from the previous month.
Among the 19 countries that share the single currency, Ireland suffered the biggest fall in production output, down 7.5%, while the core economies of Germany and France also showed a decline, down 1.1% and 1.2% respectively.
Month-on-month industrial production fell 0.6% in June after a 1.2% rise in the previous month.
A decline had been expected after May's particularly robust performance, but the 0.6% fall was worse than the forecast 0.5% decline.
On an annualised basis, production rose by 2.6%, slowing from May's 3.9% pace and lower than the 2.8% forecast by analysts.
Of the countries within the eurozone where output continued to increase, Estonia, Croatia and the Netherlands experienced the greatest growth, with all three climbing 1.2%.
While the production of capital goods fell 1.9% and durable goods fell 1.2%, the strongest area of growth was in the production of energy, up 5.1%.
GDP growth impact
"This is a disappointing headline, but it is unlikely to force a downward revision of second quarter GDP data," said Claus Vistesen at Pantheon Economics.
He added: "Robust data in April and May mean that production jumped 1.2% quarter-on-quarter in Q2, and this week’s June trade data likely will show that the drag from net exports was less severe than initially estimated."
Bert Colijn, senior eurozone economist at ING said: "This false start to the quarter was also seen in other surveys, which could mean that 3Q GDP will be a touch weaker than the first half of the year.
"But", he added "that would still lead to a healthy 2% annual GDP growth rate for 2017. No need to become pessimistic about the eurozone just yet."
After several days of geopolitical tensions between the US and North Korea causing market ructions, there was a more buoyant feel at the beginning of the new week.
The EuroStoxx 50 index was 1% higher in late morning trade, while the euro was higher against the pound and the yen.
The single currency failed to gain traction against the dollar, however, which climbed 0.2% to $1.18.
