US futures higher as Dow tries to extend gains

Wall Street looked set to open higher on Tuesday, as global stock markets continued rising as a result of steadying crude oil prices.

The Dow Jones industrial average on Monday closed above 18,000 for the first time since July and both Asian and European stock indexes traded higher Tuesday.

Brent and light crude oil futures held more than 1 percent higher early Tuesday, following a volatile 24 hours. Oil prices originally fell by around 5 percent after the "no-deal" in Qatar over the weekend after recovering partly due to reports that an oil workers' strike in Kuwait could substantially knock output.
