Police in Austria say the bodies of 71 people, believed to be migrants, were discovered in an abandoned lorry found near the Hungarian border on Thursday. The victims included 59 men, eight women and four children who are thought to have been dead for about two days. Officials said the group appeared to be migrants from Syria and probably died after suffocating in the vehicle. Police in Hungary say they have arrested four people - three Bulgarians and one Afghan - linked to the lorry.
