European stocks rose, rebounding from a one-month low, as Federal Reserve Bank of Atlanta President Dennis Lockhart said the central bank is committed to its stimulus program.

The Stoxx Europe 600 Index climbed 0.3 percent to 299.59 at the close. The benchmark gauge fell to the lowest level since May 2 yesterday amid speculation the Fed will scale back bond buying.

Lockhart said late yesterday that recent data suggest the economy lacks the strength to justify a reduction in the central bank's bond-buying program. "To the extent that the markets are seeing mixed messages, it simply reflects the debate that's going on among the colleagues on the Federal Open Market Committee," Lockhart said in a interview. "The bigger picture is that any adjustment is not a major policy shift."

National benchmark indexes climbed in 12 of the 18 western European markets.
