LONDON (MarketWatch) -- European stocks finished flat Friday, and ended with losses for the week, during which concerns about euro-zone growth were underscored.

The Stoxx Europe 600 index rose less than 1 point at 341.97. It fell by 1.8% for the week, the biggest weekly pullback since mid-April, according to FactSet data.

A run of lackluster data from the euro zone continued Friday with France's government saying growth in gross domestic product stalled in the first quarter and inflation in Spain was flat this month, highlighting worries about the risk of deflation.

Meanwhile, a European Commission survey found there was a decline in confidence in the region among businesses and households in June. The dampened sentiment prevailed even as the European Central Bank this month launched measures aimed at staving off sharply low levels of inflation and reviving economic growth. The commission's Economic Sentiment Indicator fell to 102.0 from 102.6 in May, falling short of the expected rise to 103.0 in a Wall Street Journal poll of economists.

The ECB will issue its next policy statement on Thursday.

Rolls-Royce Holdings PLC shares picked up 2.2% after a Reuters report that Airbus Group is near a decision to upgrade its A330 aircraft with engines made by Rolls-Royce.

Ophir Energy dropped 5.4% following a ratings downgrade to neutral from buy at UBS. The British oil exploration company on Thursday issued a disappointing update about a dry well in offshore Gabon.

Shares of Barclays PLC (BCS) pared their gain to 0.5%. They dropped Thursday by 6.5% to a 19-month low on U.S. legal problems. Barclays Chief Executive Antony Jenkins said in a staff memo Thursday that the bank will conduct an internal probe following accusations of fraud in a lawsuit filed by the New York Attorney General, according to reports.

Late Thursday, The Wall Street Journal reported that major brokers are closing their connections to a dark pool run by Barclays in the wake of the lawsuit, according to people familiar with the matter.
