* Gold near 3-week low on falling oil
* Platinum rebounds from lows but demand fears linger (Updates prices, adds activity in physical sector)
By Lewa Pardomuan
SINGAPORE, July 30 (Reuters) - Gold fell further on Wednesday, hovering near its lowest level in three weeks after oil prices extended their slide, but tensions in the Middle East could spur safe-haven buying at lower levels.
Platinum bounced from lows but fears of falling demand for autocatalysts from auto makers due to the slowing U.S. economy and a lack of buying interest from jewellery makers weighed on sentiment.
Gold <XAU=> dipped to $917.30/918.30 an ounce from $918.80/920.30 an ounce late in New York. It fell as low as $913.80 an ounce on Tuesday, its weakest since July 8, also driven by rebounding stocks and a firmer U.S. dollar.
"As long as the Iran issue is not settled, gold and oil prices will not decrease too much. For gold, $900 is the bottom price at this moment," said Yukuji Sonoda, analyst at Daiichi Commodities in Tokyo.
Iran's president called on Tuesday for developing nations to unite against what he said was bias by the U.N. Security Council, which the Islamic Republic accuses of siding with the West in a nuclear row. [
]The United States and Israel have not ruled out military action if the Iran nuclear row cannot be resolved by diplomacy.
Dealers noted early selling from Japanese investors but short covering as well as light buying from jewellery makers in other parts of Asia helped bullion rebound from early lows.
"Upside potential remainsthis week to try $935 or higher price levels," said William Kwan, bullion director at Gold Capital Management in Singapore.
"Gold and silver hit a low of $914 and $17.04 and buying interest quickly emerged asbuyers find the price to be a fair value to golong just above round number supports of $900 and $17," he said.
Oil <CLc1> eased 11 cents to $122.08 a barrel, well below a record of $147.27 hit on July 11, as OPEC signalled no production cuts and the dollar gained against other currencies. [
]Spot platinum <XPT=> rose to $1,739.00/1,759.50 an ounce from $1,735.50/1,755.50 late in New York -- far off a record high of $2,290 hit in March.
Despite lower prices, manufacturers in China and Japan were not too keen to buy because of high inventories blamed on unsold jewellery, said Sonoda of Daiichi Commodities.
"They are not in a position to buy. They also presume the price will decrease further," said Sonoda, who pegged support at $1,650 an ounce.
China's platinum imports dropped more than 4 percent to 15,871 kilograms in January to June 2008 compared with the same period last year, official customs figures show. China is the world's largest platinum jewellery consumer.
New York gold futures <GCQ8> added $0.50 to $917 an ounce.
The most active Tokyo gold contract for June 2009 delivery <0#JPL:> on the Tokyo Commodity Exchange ended the morning session 26 yen per gram lower at 3,215 yen.
Spot palladium <XPD=> rose to $381.00/386.00 an ounce from $380.00/388.00 late in New York. Silver <XAG=> edged down to $17.28/17.35 an ounce from $17.32/17.38.
