April 21 (Reuters) - Gold extended losses on Tuesday as a stronger dollar and rising yields weighed on prices, while investors awaited the outcome of tentative U.S.-Iran talks and Federal Reserve Chair nominee Kevin Warsh's confirmation hearing.

Spot gold fell 2.2% to $4,712.04 per ounce at 1:46 p.m. EDT (1746 GMT), its lowest in over a week. U.S. gold futures for June delivery settled 2.3% lower to $4,719.60.

"Stronger yields and the dollar are putting pressure on gold, along with a lot of headlines and mixed signals coming out about the Iran situation, causing energies to move higher, putting pressure on metals," Bob Haberkorn, senior market strategist at RJO Futures said.

President Donald Trump said on Tuesday that he did not want to extend the expiring ceasefire on Iran and that the U.S. military was "raring to go" if negotiations collapsed, which drove crude oil prices up more than 3%. [O/R]

The surge in oil prices after the U.S. and Israel launched the war against Iran on February 28 has stoked fears of a spike in inflation, dimming the outlook for rate cuts.

While gold is seen as an inflation hedge, the non-yielding asset suffers when interest rates are high.

Meanwhile, investors were focused on a Senate Banking Committee hearing regarding the confirmation of Former Fed Governor Kevin Warsh as Fed chief.

Warsh called for "regime change" at the U.S. central bank, including a new approach for controlling inflation and a communications overhaul that may discourage his colleagues from saying too much about the direction of monetary policy.

"Traders will be watching and listening very closely to (Warsh's) comments. With that hearing, you should expect lots of ups and downs in volatility," Haberkorn added.

Among other precious metals, spot silver fell 3.9% to $76.76 per ounce, platinum lost 2.7% to $2,033.37, while palladium was down 0.6% at $1,541.56.
