Later, Vettel lost his second-place finish after being disqualified by stewards for a fuel irregularity, a stewards' statement said.
The German, who crossed the line 1.8 seconds behind first-time race winner Esteban Ocon, did not have enough fuel left in his Aston Martin to provide a sample after the race as required by the rules.
The decision moves Lewis Hamilton up to second, handing the Mercedes driver an eight-point lead over title rival Max Verstappen, who moves up to ninth.
