Two suspected human traffickers, have been arrested and jaild in Serbia after authorities in Paraguay discovered the bodies of seven men in a shipping container. Serbian officials believe the suspects tried to get the men into the EU.

The suspects, a Moroccan man and an Algerian man, were jailed after Paraguay officials found decomposing bodies in a shipment of fertilizer, Serbian police said on Thursday.

Serbian authorities said the two men were ‘suspected of plotting with other unidentified persons to place migrants in a railroad transport container.’

The suspects allegedly aimed to illegally move seven stowaways from Serbia to neighboring Croatia which is an EU member, unlike Serbia. However, the container ended up in Paraguay where the remains of the seven men were discovered last week.

While commenting on the discovery, Paraguay officials said they found enough food and water for 72 hours.

The Serbian officials said the detainees would face charges of people smuggling, but no charges were laid over the migrants’ deaths.

Serbia is located on the so-called Balkan migration route, which saw over a million refugees and asylum seekers try to gain access to rich EU countries during the 2016 peak of the refugee crisis.

According to Infomigrants, some 6,000 migrants are still located in Serbia today, with the overwhelming majority hoping to eventually carry on their journey towards western EU.
