Vettel now has 272 championship points, ahead of Alonso with 195
Red Bull's Sebastian Vettel has secured his fourth F1 victory in a row, following an eventful Korean Grand Prix.
Vettel had secured pole position during qualifying, with Hamilton and Webber behind. The Red Bull ace charged forwards from the start, predictably securing himself an early lead. Shortly after Massa span his Ferrari, causing a fracas in which both Sutil and Button picked up wing damage.
Both Grosjean and Hamilton then spent the first half of the race trying to catch an increasingly quick Vettel. Tailing the lead three were Rosberg, followed by Hulkenberg, Alonso and the remainder of the pack.
As the race progressed, Hamilton's tyres began to wear at an excessive rate, causing the gap between his Mercedes and Grosjean's Lotus to grow. With Hamilton's pace declining, his team-mate Rosberg went to overtake only for his front wing to collapse, slowing his Mercedes.
Raikkonen seized the opportunity, gaining two places before the safety car was called out after Perez's right-front tyre disintegrated, shedding debris across the track. Webber, who was following behind Perez, hit the debris and picked up a puncture.
Following the restart, Vettel accelerated away from Grosjean and Raikkonen, the Lotus pair swapping places following a bold overtaking move a lap later.
Sutil then spun, slamming in to Webber. His Red Bull promptly caught fire in the run-off area, causing some alarm as a firefighting vehicle entered the circuit without a preceding safety car.
With the fire extinguished, the truck off the track and the race back underway, Vettel pulled away from Raikkonen and Grosjean again to finish first.
Vettel was joined on the podium by Raikkonen, in second, and Grosjean, third. Vettel currently leads the championship with 272 points, followed by Alonso with 195 and Raikkonen with 167.
The next F1 race takes place on 13 October, in Japan.
