NEW YORK, Sept 6 (Reuters) - U.S. crude oil futures advanced Friday on the prospect of a possible Western-led military strike against Syria and as traders bought contracts to cover short positions ahead of the weekend amid concerns military action would cause a spike in oil prices.
U.S. Congress will vote next week on President Barack Obama's proposal to launch a missile strike to punish Syrian President Bashar al-Assad for his suspected use of chemical weapons against civilians.
At the G20 summit in St Petersburg, Obama has faced growing pressure from Russia, China, the European Union and major emerging market countries not to carry out a strike without support from the U.N. Security Council.
But Obama said failure to act against Syria's use of chemical weapons would embolden "rogue nations" to use them too. Obama said he would address the American people on Syria on Tuesday.
Obama declined to say whether he would proceed with a strike against Syria even if Congress votes "No."
Brent oil, the global benchmark has already priced in concern that a potential U.S. strike on Syria would spread unrest and disrupt Middle East oil supplies.
U.S. oil was playing catch up on Friday, said Rich Ilczyszyn, chief market strategist and founder of iitrader.com LLC in Chicago.
"Right here you have speculators in WTI. Brent was already pricing in the action, that's why you see a bigger bid in WTI."
Brent crude oil futures for October delivery were trading 89 cents higher at $116.25 per barrel at 10:33 a.m. EDT (1433 GMT).
U.S. crude oil for October delivery was last trading $1.90 per barrel higher at $110.28.
U.S. crude extended slight gains after the Labor Department said nonfarm payrolls increased 169,000 last month, but the jobs number was less than the market expected.
Rising U.S. oil prices narrowed Brent's premium to U.S. crude oil to $5.66. The spread <CL-LCO1=R> was last trading at $5.85.
