LONDON—Crude-oil futures fell, tracking European equities as the dollar strengthened and investors worried about Europe's debt crisis.
In late morning, the front-month November Brent contract on London's ICE futures exchange was 69 cents, or 0.6%, lower at $108.26 a barrel. The front-month November contract on the New York Mercantile Exchange was trading down 64 cents, or 0.8%, at $84.77 a barrel.
Slovakia's Parliament votes Tuesday on expanding the euro zone's rescue fund. The country is the last of the currency bloc's 17 members to vote.

Oil prices were supported by news of a strike in Kuwait, which affected oil exports Monday but has since ended. Shell also declared force majeure on shipments of Forcados crude from Nigeria, saying it wasn't able to make deliveries because of pipeline sabotage.
A stronger dollar tends to weigh on oil because prices are in dollars. As the dollar rises, oil becomes more expensive for holders of other currencies.
The ICE's gasoil contract for October delivery was down $10.25, or 1.1%, at $907.75 a metric ton, while Nymex gasoline for November delivery was 86 points lower at $2.6867 a gallon.
