FIA to review 'unbelievable' Senna exit.

Motorsport's governing body has said that it will review security measures at the Istanbul Park circuit after Bruno Senna was taken out of Sunday's GP2 Series sprint race by a collision with a stray dog.

In a moment reminiscent of the 1960s and '70s, two animals got onto the track during the 23-lap event, causing several drivers to take avoiding action before Senna made contact with one on the back straight.

"The race was going really well up until the dog incident," the Brazilian said, having charged up to sixth place from 15th on the grid, "I made a good start, kept out of trouble and seized every opportunity that came my way - without taking any risks. The car was really good and I knew we could score some useful points.

"I was following Mike Conway quite closely when he suddenly moved to the right. I thought he had a problem, so I went to the left... and that's when I saw the dog for the first time. It ran right, so I went left, but then it turned again, hit my wheel and that was that. I couldn't believe it."

Fortunately, Senna was unhurt in the impact, which was estimated to have occurred at about 150mph, but his car sustained significant damage to its front-right corner, causing his retirement.

Concerned about the implications of a repeat during the afternoon's Formula One event, the FIA instructed security staff to check on all access points to the complex and remove any animals found within the perimeter. All access points to the circuit were closed ahead of the grand prix, which passed off without incident.

Charlie Whiting has requested that a formal review and report by submitted to the FIA by the circuit, which is operated by Bernie Ecclestone.
