UPDATE 4-Oil firmer above $115 after US job growth misses forecast
* World leaders pressure U.S. over Syria at G20 summit
* U.S. Cushing crude stocks fall to lowest in 18 mths -EIA
* U.S. jobs growth misses expectations, may delay Fed tapering
(Adds U.S. jobs data)
LONDON, Sept 6 (Reuters) - Global oil prices firmed above $115 a barrel on Friday, after lower-than-expected U.S. jobs growth data prompted talk the Federal Reserve could delay moves to unwind a massive stimulus programme that has boosted commodities.
Concern that a potential U.S. strike on Syria would spread unrest and further disrupt Middle East supplies has boosted oil prices in recent weeks and benchmark Brent crude oil is heading for a fourth straight weekly rise.
Gains have been limited, however, as U.S. President Barack Obama comes under growing pressure from other leaders not to order a military strike on Syria due to fears that it would hurt the global economy and push up oil prices.
Nonfarm payrolls increased 169,000 last month, the Labor Department said on Friday, adding to signs that economic growth may have slowed a little in the third quarter and complicating a keenly-awaited Federal Reserve decision on whether to scale back its stimulus programme later this month.
October Brent rose 51 cents to $115.77 a barrel by 1320 GMT after the jobs report. U.S. WTI crude oil for October delivery rallied by $1.18 to $109.55 on the data.
"The moment of reckoning is quickly approaching as the announcement of a change in monetary policy by the Federal Reserve gets increasingly close," PVM analysts wrote in their fundamentals report.
Oil could face downward pressure when the U.S. Federal Reserve starts rolling back its stimulus programme, tightening liquidity in global markets and strengthening the dollar.
A strong dollar may depress oil as dollar-priced commodities become less affordable to holders of other currencies.
Solid U.S. jobs and service sector data on Thursday bolstered views the Fed could start slowing its bond-buying programme as soon as this month, but the jobs data highlighted uncertainty around the economic outlook.
SYRIA CONCERNS EBB
Receding expectations of an imminent U.S. strike on Syria coupled with a fall in crude stockpiles at WTI's delivery point in Cushing, Oklahoma, have also seen the spread between Brent and WTI narrow to $6.76.
In less than two months, Brent's premium over U.S. crude had swung from parity to as wide as $9, a level not seen since early June, due to concern about Middle East supply disruptions.
Syria is not a major oil producer but concerns had mounted that an escalation in the conflict there could suck in big exporters such as Iran or disrupt shipping routes.
"I don't think Brent will do much today. The G20 seems deadlocked over Syria. This U.S. vote next week could go either way so everyone is waiting," Michael Hewson, analyst at CMC Markets, said.
U.S. Congress will vote next week on Obama's proposal to launch a missile strike to punish President Bashar al-Assad for his suspected use of chemical weapons against civilians, but scores of lawmakers remain undecided.
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.
