A monster truck plowed into a crowd of onlookers Sunday killing at least two and injuring dozens at an automotive show in Haaksbergen, Netherlands. NL Times reported the driver gunned the truck's engine to power over six cars before losing control of the vehicle when it careened around a curve and jumped a metal railing.

Expatica.com reported 18 people were injured, six seriously. Dutch television reported rescue vehicles came from as far away as Germany.

Police said they're investigating the incident and have detained the truck's driver.

Mayor Hans Gerritsen said one child and two adults were killed, the Associated Press reported quoting Dutch national broadcaster NOS. Police, however, put the number of dead at two.
