A smuggling vehicle crammed with asylum-seekers crashed on a northern Greek highway Friday killing six people, including three children, and severely injuring a further four adults. Police said the jeep was carrying 16 men, women and children when it veered off the road and crashed into rocks near the town of Kavala. There of the survivors were in hospital with severe head injuries, another was being operated on for bone fractures, while the remaining six were more lightly injured, AP reported. The driver, who was a member of a migrant-smuggling gang paid to ferry the asylum-seekers west, was among the dead.
