NEW YORK, Nov 19 (Reuters) - Brent futures slipped on Tuesday as investors eyed talks this week between world powers and Iran that could lead to an easing of sanctions against the oil-rich country.
Gasoline and heating oil prices rose after an explosion at Total's Antwerp 360,000 barrel per day (bpd) refinery in Belgium, Europe's second-largest, killed at least one person and halted gasoline production.
"Heating oil is up, and it's moving pretty well with the market," said Bill Baruch, senior market strategist at iitrader.com in Chicago, Illinois.
" 1/8The explosion 3/8 probably gave it a little bit of a boost."
January Brent crude fell 35 cents to $108.12 a barrel by 11:10 a.m. EST (1610 GMT), down for the third straight session. U.S. crude for December rose 7 cents to $93.10 after earlier falling to a fresh four-month low of $92.43.
RBOB gasoline futures broke Monday's session high, rose by as much as 2.19 cents to a high of $2.6787 per gallon. Heating oil also rose 0.5 percent to $2.9375 per gallon.
The six major world powers and Iran will meet from Wednesday to try to forge an interim deal on Tehran's nuclear program.
U.S. Secretary of State John Kerry on Monday pressed Iran to finalize a deal, but said he has "no specific expectations" for talks in Geneva.
