SOFIA, Bulgaria >> Police in Bulgaria on Friday discovered an abandoned truck containing the bodies of 18 migrants, who appeared to have suffocated to death.

The Interior Ministry said that according to initial information, the truck was carrying about 40 migrants, and the survivors were taken to hospitals for emergency treatment.

Bulgarian Health Minister Assen Medzhidiev said most of the survivors were in very bad condition.

“They have suffered from lack of oxygen, their clothes are wet, they are freezing and obviously haven’t eaten for days,” Medzhidiev said.

The truck was found abandoned on a highway near the capital, Sofia. The driver was not there, but police discovered the passengers in a secret compartment below a load of timber.

Authorities did not immediately give the nationalities of the migrants. Bulgarian media reported they all were from Afghanistan.
