NEW YORK, Oct 10 (Reuters) - Oil prices edged up in choppy trading on Wednesday, as concerns about the security of Middle East supplies amid escalating tensions over Syria helped offset fears that slowing economic growth will curb demand for petroleum.

U.S. and Brent crude rallied briefly, testing resistance at recent price peaks. U.S. crude came within 17 cents of the 50-day moving average of $93.83, a technical area monitored by chart-watching traders and analysts.

The euro briefly turned higher against the U.S. currency and the dollar index weakened slightly, lending support to dollar-denominated crude oil.

Shelling along the Turkey-Syria border, hostility between Iran and the West and an impending Israeli election have reinforced fears about potential threats to oil supplies from the Middle East Gulf.

Turkey's military chief of staff said on Wednesday his troops would respond with greater force if bombardments from Syria kept hitting Turkish territory.

"It's not that Syria and Turkey are significant oil exporters but Iraqi crude from the northern part of Iraq (Kirkuk) flows via pipeline through Turkey to Ceyhan," said Dominick Chirichella, an energy analyst at New York's Energy Management Institute.

Brent November crude rose 30 cents to $114.80 a barrel by 11:58 a.m. EDT (1558 GMT), having reached $115.59, the highest since prices hit $117.02 on Sept. 1, according to Reuters data.

U.S. November crude was up 20 cents at $92.59 a barrel, after rising to $93.66, the highest since prices reached $93.84 intraday on Sept. 21.

U.S. crude tested resistance above the $93.33 peak from Oct. 1, after prices had stalled in consecutive sessions at intraday highs of $93.18 and $93.20 on Sept. 24 and 25.

Oil prices came under early pressure from continuing worries about economic growth after the International Monetary Fund said risks to global financial stability had risen in the past six months, leaving confidence "very fragile".
