Scotland's Dario Franchitti has won the 91st running of the Indianapolis 500 after the race was halted by rain after 165 of the 200 scheduled laps.

With speeds of 220mph, the cars are not allowed to race when it rains, and Franchitti held the lead when storm clouds closed in for a second time.
New Zealand's Scott Dixon was second with Brazilian Helio Castroneves third.
Danica Patrick finished seventh while England's Darren Manning came 20th and Dan Wheldon, who won in 2005, 22nd.
"I can hardly believe it," said Franchitti, who became the first Scot to win the race since Jim Clark in 1965.
"Who could have thought it? Now I know what it means to win this race.
"We cut a tyre on some debris and had to make a pit stop on lap 143. I was trying to save fuel but when it went green, I had to go.
"I can't believe it. I have to thank my whole team. This is awesome. To be a member of this club is fantastic."
His wife, the actress Ashley Judd, said: "My husband is gifted. I told him, 'Babe, just pick them off.' He raced to 14th to first like a gentleman. I'm so proud of him. This is so overdue for him."
Rain had already caused a three-hour stoppage after 113 laps with Brazil's Tony Kanaan in the lead.
Had the rain stayed, Kanaan would have been declared the winner as the result becomes official once more than 100 laps have been completed.
I'm one lucky guy - it was definitely the big one
But the weather cleared up and Franchitti took the lead when Kanaan and defending champion Sam Hornish Jr pitted 10 laps before the rain hit.
At that stage Franchitti only had enough fuel for about another 10 laps, and had the rain stayed away he would have had to stop in order to complete the race.
But racing was suspended when his team-mate Marco Andretti was involved in a multi-car crash and the rain returned to bring the race to an end.
The 20-year-old's car touched wheels with Wheldon and went into the air before landing upside down.
Fortunately, Andretti was able to climb from the wreckage with help from the safety crew.
"I'm one lucky guy," said Andretti. "It was definitely the big one.
"I was trying to fix my mirror under yellow and I had no idea he was there. I was upside-down praying to God."
