Three more people were killed yesterday on one of the country’s most dangerous stretches of road at the Maliakos Gulf on the Athens-to-Thessaloniki highway after a truck collided with two oncoming cars, police said. At about 2.15 p.m., a northbound truck entered the opposite traffic lane and collided with one of the cars. The driver of the second oncoming vehicle could not avoid the accident in time and drove into the collision. The driver of the first vehicle, 70-year-old Ioannis Prokopidis, and two female passengers Valentina Prokopidis, and Nadia Deliporanidou, aged 67 and 66 respectively, were killed. The driver of the second car sustained serious injuries and was taken to a hospital. Police said the truckdriver claimed he swerved into the opposite lane after he felt dizzy and lost control of the vehicle. The stretch of road where the accident took place curves around the Maliakos Gulf north of Athens. Car and bus accidents have claimed more than 100 lives there since 2000.
