SINGAPORE, July 24 (Reuters) - Gold struck a two-week low on Thursday, losing some of of its safe-haven appeal after oil extended losses and stock markets rose, while platinum tumbled to its weakest in six months. Platinum has been hit fears of falling demand from car makers including General Motors <GM.N> and Toyota Motor Corp <7203.T> due to a slowing U.S. economy. Autocatalysts account for around 35 percent of global demand for the metal.
Gold <XAU=> fell as low as $916.40 an ounce, its lowest since July 9, down from $921.35/922.95 late in New York on Wednesday -- well below a record high of $1,030.80 hit in March.
"Weaker oil prices, a stronger dollar, and both of those are negative for gold. I just think there's a good possibility that we might see a continuation of a fall in oil prices," said Darren Heathcote of Investec Australia in Sydney.
"I've got to say I didn't foresee gold sort of breaking through the $936 area as easily as it did. But now it's here. We've got to be targeting $912-$904 or something like that," he said.
Oil <CLc1> extended losses and hit a seven-week low of $123.98 a barrel after data showed a larger-than-expected increase in domestic U.S. gasoline stocks last week. [
]Japan's Nikkei average <

Spot platinum <XPT=> dropped to $1,721.00/1,741.00 an ounce from $1,744.00/1,764.00 an ounce. It tumbled to $1,707 an ounce on Thursday, its lowest level since late January.
"I am bearish on precious metals for now, particularly platinum and palladium. Their charts looks quite bad," said a dealer in Singapore.
"The next support is $1,684 but if we break this level, it's a long long way down to the $1,590 regions," he said.
Platinum struck a record at $2,290 in March after an electricity shortage that disrupted mining in main producer South Africa triggered speculative buying, but a combination of profit taking and demand fears erased most of the gains.
Spot palladium <XPD=> fell to $372.50/380.50 an ounce from $383.00/391.00 late in New York. It hit an intraday low of $371.50 an ounce, its lowest level since Jan. 25.
Palladium is also used in jewellery and autocatalysts.
Silver <XAG=> edged down to $17.29/17.35 an ounce from $17.33/17.38 late in New York.
Gold futures for August delivery <GCQ8> on the COMEX division of the New York Mercantile Exchange fell $4.2 to $918.60 an ounce.
The most active Tokyo gold contract for June 2009 delivery <0#JPL:> on the Tokyo Commodity Exchange fell 63 yen per gram to 3,212 yen.
