Tragedy struck on Saturday in the Asturias Karting Championships at the Fernando Alonso Circuit as a 10-year-old boy died, the Spanish Motorsport Federation have confirmed in an official statement.

Gonzalo Basurto from Burgos died following a collision with another kart in the test session ahead of the race due to be held on Sunday.

The child was initially taken to hospital in the town of Llanera before being moved to the Central University Hospital of Asturias, in Oviedo, where he died this morning.

"I woke up at dawn on one of the saddest days," tweeted Fernando Alonso earlier on Sunday.

"I'm torn apart here, a massive hug to Gonzalo's family and all in karting world."

The race has been cancelled as a result.
