* Spanish, Italian yield spreads rise to new highs
* World stocks struggle; European shares in volatile session

LONDON, Nov 30 (Reuters) - The euro hit a 10-week low against the dollar and world stocks struggled on Tuesday as euro zone debt problems weighed on investor sentiment even after Ireland's bailout.
The premium investors demand to hold Spanish and Italian sovereign bonds over German bonds hit their highest since the euro's launch while some of the region's "core" debt issuers, including France, were pressured.
An 85 billion euro package for Ireland announced on Sunday did little to stem fiscal concerns, as speculators targeted other debt-laden countries.
"Speculators are targeting Italy and Spain and are not going to stop. We haven't seen any selling from real money (accounts) yet, they're all very nervous but haven't started selling, when they do it's going to be a wash," one Italian trader said.
The spread between Spanish 10-year bond yields <ES10YT=TWEB> over those of Germany <DE10YT=TWEB> widened by 20 basis points to 297 basis points, while Italian 10-year spreads <IT10YT=TWEB> rose for a fourth day to 210 basis points.
Yields on the 10-year Spanish bond <ES10YT=TWEB> rose for the eleventh consecutive session to 5.65 percent, while Italian 10-year debt yields <IT10YT=TWEB> rose to 4.77 percent.
The euro fell as low as $1.3016, down 0.7 percent on the day, and its lowest since late September.
"The euro has had a hard fall and has not been lifted by the finalising of the Irish rescue deal," said Stephan Maier, currency strategist at Unicredit in Milan.
FRAGILE SENTIMENT
European shares drifted as concerns about euro zone peripherals weighed on sentiment. The FTSEurofirst 300 <
> index of top European shares was flat at 1,068.46 points."Sentiment remains very fragile, with difficulties in Europe still dominating and investors quick to book profits," said Keith Bowman, equity analyst at Hargreaves Lansdown.
Japan's Nikkei <
> slid 1.9 percent and the MSCI ex-Japan index <.MIAPJ0000PUS> fell 0.4 percent on Tuesday.MSCI's all country world index <.MIWD00000PUS> was down 0.2 percent on the day.
U.S. Treasury prices rose, adding to the previous day's gains, as investors turned to government debt as a safe haven from the recent flare-up in volatility.
Spot gold <XAU=> was a touch higher at $1,369 an ounce, while oil slipped, retracing part of the sharp gains in the previous session. (Additional reporting by Amanda Cooper, Atul Prakash and Jessica Mortimer, editing by Mike Peacock)
