Eurozone production grows for third straight month
Industrial production in the 16 countries that use the euro increased for the third consecutive month in May.
Eurostat, the EU's statistics office, said production climbed by 0.9% from the previous month, the same as the increase seen in April.
However, economists had forecast a rise of 1.2%.
Eurozone manufacturers have benefited from the lower value of the euro, as this makes their goods cheaper in countries outside the bloc.
This has helped manufacturers play a key role in dragging the EU out of recession.
