NEW YORK, Feb 5 (Reuters) - Oil slid below $70 per barrel on Friday as a stronger dollar and data showing additional U.S. job cuts weighed on the market.
It was the second straight session of steep declines in oil prices, which on Thursday posted their biggest one-day fall since July.
U.S. crude oil for March delivery <CLc1> briefly fell below $70 a barrel and was down $2.94 to $70.20 per barrel by 11:49 a.m. EST (1649 GMT) after reaching a low below $70. On Thursday, it touched a 2010 intraday low of $72.42 and closed down 5 percent.
London ICE Brent for March <LCOc1> fell $3.57 to $68.59.
The dollar index, a measure of the greenback's performance against six major currencies, leapt as concern deepened about worsening fiscal problems in south European countries. [

U.S. jobs data, which showed U.S. employers unexpectedly cut 20,000 in January, but the unemployment rate surprisingly fell to a five-month low of 9.7 percent, oil prices. [
]"Today's U.S. jobs report for the month of January provided a significant surprise to the downside, with a drop in the number of U.S. jobs in January by 20,000," said Jason Schenker, president, Prestige Economics, LLC, Austin, Texas.
"The big truth of today's report is not that the job market improved, which it did not. The big truth is that with downward revisions to previous employment reports, there were more jobs lost than had previously estimated," he said.
Oil fell 5 percent on Thursday, its steepest daily drop since July and the fifth-largest trading volumes ever on the New York Mercantile Exchange (NYMEX) as investors dumped risky assets.
Rumours over the health of an unidentified hedge fund were also cited as a negative factor on Thursday as the oil market fell.
On Friday, oil-focused hedge fund BlueGold denied what it said were false rumours about its continuing operations and said it was not behind oil price volatility in recent days. [

Dealers said Thursday they thought the sell-off was linked to a hedge fund unloading a big position. [

The statement from BlueGold helped calm nerves that traders said had been frayed by the sharp slide in prices.
BlueGold Chief Executive Officer Dennis Crema told Reuters he "utterly and completely" denied his company was in any way responsible for the recent volatility in crude oil prices.
"We ... deny any false rumours surrounding BlueGold's continuing operations," he added. "Business continues as usual."[
