European shares fell for the first time in three trading sessions as pressure from rising oil prices and bond yields outweighed the boost from stronger-than-expected economic activity data. According to Sina Finance, the Stoxx Europe 600 closed down 0.4%.

Energy stocks led the market, while auto and insurance shares were among the worst-performing sectors. Brent crude rose above $100 a barrel, set to end a five-session losing streak and push European government bond yields higher.

Earlier in the day, the global benchmark oil price had briefly fallen after U.S. President Donald Trump struck an optimistic tone on talks between U.S. and Iranian representatives. Separately, data showed eurozone private-sector activity expanded at the fastest pace in more than three years as the services sector unexpectedly improved, with S&P Global's September composite PMI rising to 53.1, above analysts' expectations in a Bloomberg survey.
