* Gold rises to record highs on safe-haven bid

NEW YORK, Sept 16 (Reuters) - World stocks fell on Thursday as data showed the U.S. economy's recovery remained halting, while the dollar was flat against the yen a day after Japan's huge intervention to weaken its currency.
Gold rose to a record high above $1,275 per ounce as jitters about any further yen selling and broader economic uncertainty enticed more investors to the safe-haven commodity.
U.S. government bond prices fell after Philadelphia Federal Reserve data suggested business conditions contracted in the U.S. Mid-Atlantic region in August, though not as severely as in July, while U.S. weekly claims for unemployment benefits dropped to a two-month low but still remained high.
"All the ingredients are still there, all the uncertainty and fear, to keep gold underpinned." said Robin Bhar, analyst at Credit Agricole in London.
Investors remained worried that high U.S. jobless numbers, despite falls in weekly insurance claims, would signal a slowdown in the pace of the economic recovery.
The Dow Jones industrial average <.DJI> was down 28.57 points, or 0.27 percent, at 10,544.16. The Standard & Poor's 500 Index <.SPX> was down 6.17 points, or 0.55 percent, at 1,118.90. The Nasdaq Composite Index <.IXIC> was down 12.48 points, or 0.54 percent, at 2,288.84.
The FTSEurofirst 300 <.FTEU3> index of top European shares ended 0.8 percent lower to hit its lowest closing level in a week after disappointing British retail sales in August, a sign the UK economy was on a slow growth path.
"Times are difficult because of the combination of high unemployment, banks not lending yet and governments starting to implement austerity measures. All these factors are not going to be resolved overnight," said Franz Weis, a fund manager at Comgest in Paris.
MSCI's All-Country World Index <.MIWD00000PUS> was down 0.51 percent, while Tokyo's benchmark Nikkei stock index <.N225> ended down 0.07 percent.
YEN TALK
Investors were jittery after Wednesday's currency intervention by Japan, its first in six years, that knocked the yen from a 15-year high versus the dollar. The Bank of Japan's money market data showed the yen-selling intervention may have totaled around 1.76 trillion to 1.86 trillion yen ($20.52-21.69 billion). [ID:nTKW007123]
Adding to investor nerves, Japanese Prime Minister Naoto Kan pointed to more potential yen selling.

"Things have been quiet on the intervention front so far today. Clients are hesitant at this point to touch dollar/yen in either direction," said Amelia Bourdeau, senior currency strategist at UBS AG in Stamford, Connecticut.
Wednesday's move was designed to protect Japanese exports from a too-competitive exchange rate and ward off job losses.
