The FTSE 100 <.FTSE> index is seen falling on Tuesday, tracking weakness overnight on Wall Street and in Asia, after a rise in bond yields in Italy and Spain reflected concern that the euro zone debt crisis is getting worse.

The UK benchmark looks set to shed 17 to 18 points, or 0.3 percent, according to financial bookmakers, after it closed 26.34 points, or 0.5 percent, lower at 5,519.04 on Monday, albeit in thin volumes.

Italy sold 3 billion euros of five-year bonds at 6.29 percent on Monday, a euro-era record, casting doubt on the long-term financing of the country.

Italy's 10-year bond yields rose to 6.76 percent on Monday, also pushing Spanish 10-year yields above 6 percent for the first time since the European Central Bank started to buy the country's bonds in August.

Investors showed their distress by demanding much higher yields from Italian bonds. It certainly doesn't look like the concern will dissipate any time soon, and the real worry is that if concerns over Italy gains momentum, it may be the issue that opens the floodgates, Zahid Mahmood, dealer at Capital Spreads, said.

The euro zone GDP flash estimate for July-September at 10 a.m. will come under scrutiny. If this comes in below market expectations for 0.2 percent growth from the previous quarter, it could intensify worries about the euro zone's dilemma of fiscal tightening hurting growth.
