* Oil falls on Chavez's Libya mediation proposal

* Jobless claims boost U.S. stocks
* ECB buoys euro with inflation comments (Updates prices, US payrolls details)

NEW YORK, March 3 (Reuters) - U.S. stocks charged higher on Thursday, driven by upbeat U.S. labor market data and a pullback in oil prices, while the European Central Bank president's warning about inflation triggered a rally in the euro.
Data showing new U.S. claims for unemployment benefits fell last week to their lowest level in more than 2-1/2 years was the latest optimistic reading to bolster hopes for an upside surprise in Friday's key payrolls report.
ECB President Jean-Claude Trichet's comments on inflationary risks were widely expected, but he surprised investors by saying the bank may raise interest rates as soon as next month.
The heightened concerns about inflation followed months of sharp gains in oil and other commodities.
The latest batch of purchasing managers' indexes (PMI) in Europe and elsewhere suggested fast-building inflationary pressures. For details, see [

On Wednesday, ADP data showed U.S. private-sector employers added more jobs than forecast last month. Also, a gauge of employment in a report on the U.S. services sector on Thursday rose to a near five-year high in February. [

The survey was conducted before data on Monday showed strong factory hiring, which prompted some economists to rethink their forecasts. [
]OIL AND GOLD SLIPS
Oil prices declined after Venezuela President Hugo Chavez made a proposal to broker a peace deal in Libya.
Some oil analysts suggested the Chavez proposal was a convenient excuse for traders to adjust their positions.
"If it's coming out of Chavez, it might not have a great degree of substance," said Tim Riddell, head of technical analysis at ANZ in Singapore.
"The fact that the markets have been so volatile, and without having concrete evidence of any material shift in the unrest in the Arab world, suggests to me that we are at best consolidating."
Brent crude oil <LCOc1> was down $1.72 at $114.62 a barrel. On Wednesday, crude approached 2-1/2-year highs as violence escalated in oil producer Libya.
Investors worry if it is not halted soon, the political instability could spread to major oil producer Saudi Arabia, a central U.S. ally in the region, and other oil suppliers.
