Stocks on Thursday followed crude oil higher as both a massive Canadian wildfire and fighting in Libya threatened to disrupt output.

The S&P 500 rose 0.24%, the Dow Jones Industrial Average gained 0.15%, and the Nasdaq added 0.28%.

A state of emergency was declared in Canada's Alberta province after a wildfire that began Sunday continued to threaten the region. The fire has halted production at one major mining operation in the area and reduced operations at another.

Separately, fighting between rival factions in Libya has blocked oil tankers, prompting Tripoli officials to warn that the country's oil output could fall by 120,000 barrels a day if the disruption continues.

Crude oil has suffered a prolonged period of low prices as record global production flooded an already-oversupplied market. News of a disruption to global production triggered a rally in crude on Thursday morning. West Texas Intermediate crude oil was up 4% to $45.55 a barrel.

"Crude prices are surging higher this morning as supply disruptions in different parts of the world overshadow yesterday's bearish inventory numbers from the [Energy Information Administration]," said Robbie Fraser, commodity analyst at Schneider Electric. "While these situations do not necessarily indicate long-term threats to supply, they are the types of issues that should become increasingly important for crude price movement as the supply/demand gap narrows and the market tightens due to elevated summer demand."

The energy sector was the best performer on markets Thursday. Major oilers Exxon Mobil (XOM - Get Report) , PetroChina (PTR - Get Report) , Royal Dutch Shell (RDS.A - Get Report) , and Chevron (CVX - Get Report) were all higher, while the Energy Select Sector SPDR ETF (XLE - Get Report) added 2.2%. 

The number of new claims for unemployment benefits climbed 17,000 to 274,000 in the final week of April, according to the Labor Department. The less-volatile four-week jobless claims average increased 2,000 to 258,000. The measure remains near its lowest level since 2000.

The U.S. nonfarm payrolls report will be released on Friday morning. The U.S. economy is expected to have added 200,000 jobs to nonfarm payrolls in April, slowing slightly after two months of strong growth. Nonfarm payrolls added 215,000 jobs in March and 245,000 in February.

"As U.S. growth momentum continues to slow, the fallout is expected to begin showing up in labor market activity with employment growth slowing in April," TD Securities analysts wrote in a note. "The unemployment rate should hold at 5% as a further influx into the labor force offset the gains in household employment, while wage growth should post a solid gain."

The labor report will take on added significance as it is scrutinized for what it might mean for the Federal Reserve and the timeline of the central bank's planned interest rate hikes. The Fed recently left its federal funds rate unchanged following its April meeting and will meet again on June 14-15.
