According to an anonymous source, the migrants, who said they were Afghans, were found during a routine check at the French port of Calais in the early morning. The temperature inside the lorry was just seven degrees Celsius. The two drivers, both Romanians, have been detained, while the migrants were taken to a local hospital.
