NEW YORK, Nov 23 (Reuters) - U.S. crude oil futures prices fell on Tuesday as the dollar strengthened and investors looked to less-risky assets after an exchange of artillery fire on the Korean peninsula.
Worries that Ireland's debt crisis might spread to other euro zone countries also helped strengthen the dollar.
Investors will be focusing on the release later on Tuesday of minutes from the Federal Reserve's November meeting and the first of the weekly oil inventory reports, from the American Petroleum Institute industry group, late in the day.
U.S. crude oil inventories likely fell last week as imports declined, a Reuters analyst survey on Monday showed. Crude oil stocks were expected to have fallen 2.3 million barrels in the week to Nov. 19. [EIA/S]
Distillate and gasoline stocks also were seen lower.
