Euro zone industrial production fell by more than expected in November and by the steepest amount in more than a year, new figures show.
A sharp decline of energy output was reported as well as a drop in capital and durable consumer goods.
Industrial production in the euro zone was 0.7% lower in November than in October, the European Union's statistics body Eurostat said, although year-on-year there was still a 1.1% increase.
That compared with the average forecasts in a Reuters poll of a 0.3% monthly decline and a 1.3% annual increase.
October's figures were also revised up to increases of a 0.8% month-on-month and 2% year-on-year, from the 0.6 and 1.9% readings announced a month ago.
November's monthly decline was the steepest since August 2014 and the year-on-year reading the most muted since last April.
In the 15 euro zone members for which data was available, the sharpest declines were in Portugal, Malta and the Netherlands. The biggest rises were in Greece and Slovakia.
For the zone as a whole, energy production was down 4.3%, with weather in much of northern Europe far milder than on average.
Output of capital goods and of durable consumer goods were respectively 1.9% and 1% lower.
Intermediate goods production was up 0.7% and production of non-durable goods such as food and toiletries was 0.1% higher.
Meanwhile in the wider 28-member European Union, industrial output was down 0.6% month-on-month and up 1.4% year-on-year.
