Vettel wins Indian Grand Prix, Alonso second

Red Bull's Sebastian Vettel won the Indian Grand Prix on Sunday and stretched his Formula One championship lead over Ferrari's Fernando Alonso, who was second, to 13 points with three races remaining.

The victory, from pole position, was the world champion's fourth in a row and maintained his dominance in India after winning last year's inaugural race at the hazy Buddh International Circuit from pole.

The 25-year-old German now has 240 points to 227 for Alonso, who started fifth, and his surge towards a third title in a row is beginning to look unstoppable despite the Spaniard's best efforts.

Australian Mark Webber finished third for Red Bull, complaining of a loss of KERS boost after 45 of the 60 laps and being passed by Alonso three laps later.
