* Dollar, European shares under pressure * Coming up: minutes of Fed's April policy meet at 1800 GMT (Updates throughout, changes dateline from SINGAPORE) By Clara Denina LONDON, May 21 (Reuters) - Gold was little changed on Wednesday, failing to capitalise on a weaker dollar and lower equities, while investors remained cautious ahead of minutes of the U.S. Federal Reserve's April policy meeting due later in the day. Platinum rose to near a two-month high, and palladium touched a near three-year high as labour strikes in top producer South Africa dragged on for a 17th week and after an industry report said a shortage of both metals was set to widen this year. "For palladium, it is the perfect storm of conditions. It's the South African supply side, which in our estimate cost 600,000 ounces of lost palladium since the start of the strike, Russia and also the investment demand story," Mitsubishi Corp analyst Jonathan Butler said. Spot gold was down 0.1 percent at $1,292.56 an ounce by 1016 GMT, while U.S. gold futures were unchanged at$1,294.30 an ounce. Platinum rose 1.2 percent to $1,477.74 an ounce, not far from a two-month high of $1,483.50 hit last week, while palladium was up 0.2 percent at $815.30 an ounce, having touched its highest since August 2011 at $828.20 in earlier trade. European shares were under pressure on Wednesday, spooked by overnight falls on Wall Street, while the dollar was on track for a sixth losing session against the yen and down 0.1 percent against a basket of currencies.
