GLOBAL MARKETS-Growth worries weigh on shares, Mid East tension lifts oil

* European shares lower as China moves to support growth

* Oil jumps on supply concerns as Middle East tension mounts

* Uncertainty over Spain keeps euro steady around $1.2975

LONDON, Oct 9 (Reuters) - A warning about the global growthfrom the IMF sent European shares lower for a second day onTuesday despite a move by China to support its flagging economy,while escalating tensions between Turkey and Syria in the MiddleEast sent oil higher.

The FTSEurofirst 300 index of top European sharesfell 0.2 percent at 1,098.80 points, adding to a loss of 1percent on Monday, with share markets in Germany , andthe UK between 0.2 and 0,5 percent lower

The falls came after the International Monetary Fund cut its2012 global growth forecast to 3.3 percent from 3.5 percent,just a day after the World Bank reduced its outlook for EastAsia. The IMF also warned that a failure by U.S. and Europeanpolicymakers to fix their problems could prolong the slump.

The worries offset the positive mood in Asian markets whichfollowed China's injection of around $42 billion of cash intomoney markets, boosting speculation it may soon do more tosupport slowing growth.

"Given the softness in the economy and given where inflationis, there is certainly scope for China to be more active on thepolicy front," said Ian Richards, global head of equitiesstrategy at Exane BNP Paribas.

Meanwhile a warning from Turkish President Abdullah Gulthat the worst case scenarios between his country and Syria arenow playing out sent Brent crude oil towards $113 a barrel.

"Right now the market is concerned about the continuingconflict between Syria and Turkey, and the worry is that if itescalates, it may disrupt supplies," said Ker Chung Yang, seniorinvestment analyst at Phillip Futures in Singapore.

The most active Brent futures contract was up 0.5percent to $112.48 per barrel while its premium over U.S. oil

jumped to $22.5 per barrel, the highest since Oct. 20last year.

Elsewhere uncertainty over Spain was keeping the euro on theback foot and supporting German government bond prices.

Euro zone ministers said on Monday Spain did not need abailout yet, dashing investors' hopes they might inch closer toa resolution of the country's debt problems.

The euro bought $1.2975 , little changed from lateU.S. levels but almost a full cent below a two-week high of$1.3072 hit on Friday.

German bond futures were 16 ticks higher at 141.55in early trade while yields on Spanish 10-year bonds wereslightly higher at 5.75 percent.
