Kevin Harvick denies Kasey Kahne in gruelling NASCAR race

Kevin Harvick snatched Charlotte NASCAR Sprint Cup victory from Kasey Kahne at the end of a gruelling 600-mile race interrupted by two red flags.
Kahne had led 156 of the 400 laps and was as much as six seconds clear of the field at times in his Hendrick Chevrolet.
But he was wrong-footed by a caution for debris with 16 laps to go.
While Kahne stayed out, every other car on the lead lap pitted for at least two fresh tyres.
At the restart, Harvick's Childress Chevrolet got the jump on Kahne and pulled clear to win by a second and a half.
Kahne hung on for second, fending off Kurt Busch, Denny Hamlin and Joey Logano.
Third was a case of what might have been for Busch. He was leading when a violent tangle between Jeff Gordon, Aric Almirola, Mark Martin and Ricky Stenhouse Jr brought out the second red flag of the night.
Busch struggled to restart afterwards and had to pit for a new battery, rejoining at the tail of the lead lap pack.
His brother Kyle Busch suffered even worse luck.
The Joe Gibbs driver, Kahne and Matt Kenseth had taken turns to dominate in the opening half of the race.
Busch was at the centre of the bizarre first stoppage, when the cable for an overhead TV camera fell onto the track, damaging his and several other cars.
NASCAR stopped the race so that those affected could carry out repairs without losing position.
That kept Busch's patched-up car among the leaders, but it later suffered an engine failure.
Kenseth's chances faded when he was caught up in a late tangle involving Jimmie Johnson, Juan Pablo Montoya and Paul Menard.
There were several other big incidents in a race that took over five hours to complete.
Dale Earnhardt Jr's engine blew at the same moment as Busch's, dropping an oil slick that sent Greg Biffle, Travis Kvapil and Dave Blaney into the wall.
Champion Brad Keselowski tangled with Danica Patrick while they ran three-wide with Stenhouse.
That left Keselowski classified 36th, while Johnson was only 22nd, allowing 11th-placed finisher Carl Edwards to gain a little ground in the points.
Among those that stayed out of trouble, Ryan Newman and Tony Stewart gave the struggling Stewart-Haas squad some encouragement with sixth and seventh.
Waltrip duo Clint Bowyer and Martin Truex Jr were lead contenders at times before finishing eighth and ninth, ahead of Marcos Ambrose, another man whose car was struck by the camera cable.
