SINGAPORE, Sept 17 (Reuters) - U.S. oil futures fell for a third session running to touch two-week lows on Tuesday after a diplomatic resolution to the Syrian crisis calmed worries that crude supply from the Middle East would be at risk.
* U.S. crude for October delivery was down 72 cents at $105.87 a barrel by 0047 GMT, after hitting a session low of $105.72, its cheapest level since Sept. 3.
* Brent crude for delivery in November fell 47 cents to $109.60 per barrel, after touching a near one-month low of $108.73 in the previous session.
* Brent dropped 2.4 percent on Monday, its steepest single-day decline since June 20 after the United States agreed to call off military action against Syria in a deal with Russia to remove Damascus's chemical weapons.
* But the U.S., Britain and France warned President Bashar al-Assad that there would be consequences if he failed to hand over Syria's chemical weapons and said a U.N. report on the Aug. 21 sarin gas attack left little doubt that Assad's forces were to blame.
* Iran said it wanted to settle a decade-old nuclear dispute with the West that has raised fears of a new Middle East war, but the United States said it must back words with action.
* The Federal Reserve begins its two-day meeting later on Tuesday and is expected to cut its monthly $85-billion bond purchases by at least $10 billion, which could fuel further weakness in oil prices.
* Libya took the first steps towards restarting some of its oil output as the government said a tentative deal with protesters in the country's west allowed pumping to resume from a major field.
* Asian shares slipped and the dollar treaded water as global markets braced for the outcome of the Fed's two-day policy meeting at which it is widely expected to begin withdrawing stimulus.
