LONDON — Formula 1 president Stefano Domenicali says the current world championship could end in Europe if the war in the Middle East affects races planned in Qatar and Abu Dhabi at the conclusion of the season. “For us today, the races in Qatar and Abu Dhabi are confirmed,” he said in comments published by the Formula One website following last week’s Hungarian Grand Prix. Domenicali did not say where exactly the final races planned in November and December would be held if those in Qatar and Abu Dhabi are canceled. He added that in any case plans remain to have 24 Grand Prix races next year. The next race is the Dutch Grand Prix on Aug. 23.
