NEW YORK, Oct 8 (Reuters) - Oil prices eased on Monday on concerns that slower economic growth in China and the debt crisis in Europe will curb demand for petroleum, while the potential for Middle East turmoil to disrupt supplies limited losses.
Crude futures encountered pressure when the World Bank cut its economic growth forecasts for East Asia and the Pacific region and said there was a risk the slowdown in China, the global No. 2 oil consumer, could be deeper and more prolonged than expected by many analysts.
China's economic growth and demand for petroleum have been key supports for oil prices since elsewhere global energy demand and economic growth were slowed by recession after the financial crisis in 2008.
Worries about Spain and Europe's debt crisis continued even as euro zone officials gathered in Luxembourg to launch the region's bailout fund. The euro retreated from a two-week peak against the dollar and yen.
The concerns about Asia weighed on global and U.S. equities.
More exchanges of fire between Turkey and Syria on Monday and better-than-expected German export data helped limit oil market losses, analysts and brokers said.
"The situation between Turkey and Syria and some German export data, that was unexpectedly supportive, helped pull prices off lows hit because of concerns about China's slowing and Europe's debt crisis," said Phil Flynn, analyst at Price Futures Group in Chicago.
Brent November crude slipped 20 cents to $111.82 a barrel at 11:29 a.m. EDT (1529 GMT), recovering after falling to a session low of $110.54.
U.S. November crude was down 50 cents at $89.38 a barrel, having slipped as low as $88.21.
Brent's premium to U.S. crude neared $23 a barrel intraday on Monday. Middle East conflicts and delays in the October loading of North Sea Forties cargoes have helped push Brent's premium to its highest since October 2011.

Turkey's military launched a retaliatory strike after Syria fired a mortar bomb into Turkey's southern province of Hatay on Monday, a Turkish state official told Reuters.
It was the sixth consecutive day of Turkish retaliation against bombardment from inside Syria, where President Bashar al-Assad's forces are battling rebels.
"The ongoing shelling of Turkey by Syria is also fuelling concerns about the conflict in Syria spreading to the neighboring country," said Carsten Fritsch, oil analyst at Commerzbank in Frankfurt.
"If this were to happen, oil production in the North of Iraq would be at risk, since the oil is transported to the West via pipelines through Turkey," he said.
Iran's dispute with Israel and the West over Tehran's nuclear program also continues to limit oil price losses.
Iran on Monday derided Israel's air defenses as feeble, citing a drone incursion into Israeli airspace, but Tehran did not say it had sent the aircraft shot down by the Israelis at the weekend.
Iran also accused Israel and others of masterminding what it said was a cyber attack on communication networks on Iranian offshore oil and gas platforms in the past few weeks.
