European stocks remained under pressure Friday, weighed down by a sharp selloff on Wall Street overnight.

The Stoxx Europe 600 index extended the previous day's declines to trade 0.2% lower midmorning.

Thursday's session had turned sour after U.S. markets opened, with a combination of high stock prices, worries about the path of U.S. monetary policy and uncertainty over the global economy and conflicts sparking a 1.6% decline in the S&P 500.

"Slowing growth in China and a tightening in U.S. interest rate markets are combining to make this a frenetic month for global equity markets," said analysts at Barclays.

The selling continued in Asia, where Japan's Nikkei dropped 0.9%, but markets steadied somewhat in Europe. Germany's DAX fell 0.1% after a survey released Friday showed German consumer confidence is expected to deteriorate for a second consecutive month in October.

France's CAC 40 was 0.1% higher, and the U.K.'s FTSE 100 lost 0.3%.

U.S. stock futures pointed to a steady start for the S&P 500. Changes in futures aren't necessarily reflected in market moves after the opening bell.

In currency markets, the U.S. dollar chalked up small gains, pushing it close to the near two-year high against the euro it reached on Thursday before the equity selloff pulled it back somewhat. The euro was 0.1% lower at $1.2748.

The Russian ruble tumbled to a fresh record low against the dollar, with the currency's slide showed little sign of abating despite the cease-fire in Eastern Ukraine.

"There's a sensation in markets that the cease fire is very fragile, and people are starting to question how it's going to hold," said Ilan Solot, an emerging-market strategist at Brown Brothers Harriman.

The ruble fell more than 1% to 38.982 to the dollar.

In corporate news, banknote printer De La Rue plummeted after the firm announced a profit warning.

Air France-KLM was also among the fallers as a pilots' strike at Air France entered its 12th day.

In commodities markets, gold climbed 0.4% to $1,227.20 an ounce, and Brent crude oil lost 0.3% to $96.74 a barrel.
