Prague - Three spectators were killed Saturday when a vehicle crashed into the audience at a car race in north-eastern Czech Republic, the race organizers said.

The Slovak race driver slid in a curve near the town of Stramberk, which sent him off the race track and into the spectators, local reports said.

The victims included a 38-year-old father and his 13-year-old son, the CTK news agency reported citing a police spokeswoman.

The driver was rushed to a hospital with a slight injury, a race spokesman said in a statement.

The rally was cancelled after the accident, the cause of which is under investigation. (dpa)
