SINGAPORE, Oct 3 (Reuters) - Brent crude futures slipped towards $111 per barrel on Wednesday, hurt by persistent concerns on global growth and oil demand, while Europe's festering debt crisis added to uncertainty.

Simmering tensions in the Middle East kept losses in check, however, with investors increasingly convinced that a dispute over Iran's nuclear programme will drag on.

"It's hard to get bullish when the numbers are so bad, especially in China and the euro zone," said Tony Nunan, an oil risk manager at Mitsubishi Corp, referring to weak manufacturing data released this week.

"But prices are not going to fall that far, as the situation between Iran and Israel will keep the heat under the market until the end of the year."

Brent November crude futures had fallen 36 cents to $111.21 a barrel by 0139 GMT. They ended Tuesday below two critical technical levels -- the 50-day moving average at $112.06 and the 200-day moving average at $112.09.

U.S. November crude shed 33 cents to settle at $91.57 a barrel. It could drop below $89 per barrel after failing to break through key resistance at $93.33.

Concerns on global growth intensified this week, after a raft of manufacturing data showed that companies are yet to benefit from stimulus measures by central banks and governments.

While manufacturing in the United States grew unexpectedly in September, the euro zone's factories suffered their worst quarter in nearly three years and China appeared to have lost steam.

Adding to investor worries are next month's elections in the United States and the likelihood of a sharp cut in the country's budget deficit after the polls, which could hurt a nascent recovery in the world's biggest oil consumer.

"(Investors) have to contemplate whether such policy developments will soon result in genuine broader macro healing," Bank of America-Merrill Lynch analysts said in a report.

"We are less sanguine, especially as focus turns to a potentially negative interaction between the oncoming U.S. fiscal cliff and the peak of the election season."


Supply concerns remain heightened as an ongoing dispute over Iran's nuclear programme came back under the spotlight after last week's speeches by the heads of states of Iran, Israel and the U.S. at the United Nations General Assembly in New York.

Sanctions by the U.S. and the European Union on Iranian oil shipments have left the Middle Eastern nation's economy reeling, plunging the currency to a record low on Tuesday.

Investors are also closely monitoring elections in OPEC member Venezuela, where incumbent President Hugo Chavez is facing a strong challenge from opposition Candidate Henrique Capriles.

Venezuela's crude oil sales remain critical for the heavily indebted nation's finances.

Also supporting U.S. crude, data from the American Petroleum Institute showed that inventories rose less than expected, adding 462,000 barrels last week, compared with analysts' expectations for a build of 1.5 million barrels.

The U.S. Energy Information Administration (EIA) will release its weekly estimates later on Wednesday at 1430 GMT.
