Ferrari's Fernando Alonso won a chaotic, rain-hit Korean Grand Prix on Sunday to seize the lead in the Formula One world championship as his Red Bull rivals crashed out.
The 29-year-old Spaniard took his third victory in the past four races after pole-sitter and race leader Sebastian Vettel of Red Bull Racing was forced to retire with a blown engine on lap 46 of the 55-lap race.
The inaugural Grand Prix in South Korea finished in near-darkness after a rain-delayed start and a red flag after just three laps because of the soaked track, with the race taking almost three hours to complete.
Australian Mark Webber, the championship leader heading into the first race at the new Yeongam circuit, crashed on lap 19 when running in second position to Vettel.
It was the Red Bull driver's second non-finish of the year. Alonso's victory, 14 seconds ahead of Britain's Lewis Hamilton, was the 26th of his career, and the first in wet conditions. The next race is the Brazilian Grand Prix on November 7.
