* Gold rises on bargain hunting and firmer oil
* Platinum regains strength but holds near 11-week low (Updates prices)
SINGAPORE, July 21 (Reuters) - Gold regained some strength on Monday as oil jumped more than $1 after talks between Iran and world powers over Tehran's nuclear programme ended in stalemate, boosting the metal's safe-haven appeal.
Platinum also rebounded but held near its lowest level in more than two months on fears of falling demand. Overall trading in precious metals was slow with the absence of Japanese traders as the Tokyo Commodity Exchange was closed for a holiday.
Gold <XAU=> rose to $958.30/959.35 an ounce from $955.45/957.05 an ounce late in New York on Friday, when it fell to a one-week low of $949.50 as signs of stability in financial markets dimmed its safe-haven appeal.
Despite lower prices, demand from jewellers had yet to resurface, which suggested buyers expected a further correction following gold's steady decline since hitting a four-month high of $987.75 last week.
"I am concerned whether the $950-$955 support will hold or not. After we've seen the sharp declines in oil last week, it looks technically weak and that maybe could weigh on gold's advance," said Adrian Koh, analyst at Philip Futures.
Oil <CLc1> rose as much as $1.18 a barrel after its biggest one-week slide on record in the previous session. [

Gold futures for August delivery <GCQ8> on the COMEX division of the New York Mercantile Exchange added $0.6 to $958.60 an ounce.
Spot platinum <XPT=> rose to $1,854.00/1,862.00 an ounce from $1,846.50/1,866.50 an ounce late in New York. It struck an intraday low of $1,836.50 on Friday, its lowest level since May 2.
Platinum, a major component in autocatalysts, has been hit by fears of a reduction in car manufacturing because of a slowdown in the U.S. economy.
"I think the 1,800 support is likely to hold for now, but if it doesnt, then its very negative on platinum and we could see more declines from then onwards," said Koh of Philip Futures.
"We are starting to see a bit of a retracement as oil, gold and other commodities pull back a bit. Perhaps it's also because of a bit of a bounce in the the dollar."
Platinum has lost more than 19 percent in value since hitting a record high of $2,290 an ounce in March, when an electricity shortage in main producer South Africa triggered speculative buying.
Spot palladium <XPD=> rose to $414.00/429.00 an ounce from $411.50/419.50 late in New York. Silver <XAG=> edged up to $18.18/18.26 an ounce from $18.12/18.20 late in New York.
