NEW YORK AP-Wall Street ended another tumultuous session with a sizable gain Tuesday, partly recovering from its worst sell-off in years after the Federal Reserve said it was keeping interest rates steady. The central bank soothed fears of a worsening financial crisis even as the market waited to learn the fate of troubled insurer American International Group Inc.

In a statement accompanying its decision, the Fed noted the growing strains in the financial markets a day after the Dow Jones industrials plunged 504 points in reaction to continuing turmoil in the financial sector. The Fed also noted the ongoing weakening of the labor market. But it also sought to give some reassurance by saying it expected its policy moves to foster moderate economic growth over time.
