WASHINGTON – Crude-oil futures rose Tuesday amid persistent concerns over Iran's nuclear ambitions and after the U.S. government forecast elevated oil prices through 2007.

Light, sweet crude for June delivery rose 92 cents to settle at $70.69 a barrel on the New York Mercantile Exchange. June Brent crude futures on London's ICE Futures exchange rose 93 cents to $71.14 a barrel.
On Monday, a letter from Iran's leader to President Bush proposing "new solutions" to the tension eased market worries slightly, causing the price of Nymex crude to fall as low as $68.25 before settling 42 cents lower. But Secretary of State Condoleezza Rice swiftly rejected the letter on Tuesday and analysts said that was the impetus for prices to reverse course.

"The bulls are back in the market," said Man Financial broker Andrew Lebow.

Saudi Arabia's oil minister suggested relief — though still far off — was nonetheless in sight, saying prices will stabilize by 2010.
Speaking at a financial conference in Riyadh, Ali Naimi said the world's refining capacity would nonetheless continue to be of concern over the next four years.
"Oil production during this decade will hold steady," Naimi said, adding that the kingdom — the largest oil producer in the world — was nonetheless ready to increase its crude output if necessary.
In other Nymex trading, gasoline futures rose 4.3 cents to close at $2.0466 a gallon, heating oil futures climbed 4.06 cents to end at $1.9951 a gallon. Natural gas futures finished 11.5 cents lower at $6.581 per 1,000 cubic feet.
