NEW YORK, Oct 10 (Reuters) - Oil prices edged up in choppytrading on Wednesday, as concerns about the security of MiddleEast supplies amid escalating tensions over Syria helped offsetfears that slowing economic growth will curb demand forpetroleum.

U.S. and Brent crude rallied briefly, testing resistance atrecent price peaks. U.S. crude came within 17 cents of the50-day moving average of $93.83, a technical area monitored bychart-watching traders and analysts.

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

Shelling along the Turkey-Syria border, hostility betweenIran and the West and an impending Israeli election havereinforced fears about potential threats to oil supplies fromthe Middle East Gulf.

Turkey's military chief of staff said on Wednesday histroops would respond with greater force if bombardments fromSyria kept hitting Turkish territory.

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

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

U.S. November crude was up 20 cents at $92.59 abarrel, 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 intradayhighs of $93.18 and $93.20 on Sept. 24 and 25.

Oil prices came under early pressure from continuing worriesabout economic growth after the International Monetary Fund saidrisks to global financial stability had risen in the past sixmonths, leaving confidence "very fragile".
