Belgian Police have found twelve migrants in a refrigerated truck transporting fruit and vegetables.

The 11 Syrian men and a Sudanese man were discovered in the truck, which was travelling on a road between Antwerp and Brussels, a police spokeswoman told AFP.

She said all 12 were "in good health."  

The discovery comes as UK police continue to investigate the deaths of 39 migrants found dead in Essex, east of London, last week in a refrigerated truck which had traveled from the Belgian port of Zeebrugge.

Since then two other trucks carrying 20 migrants, all alive, have been found by Belgian authorities.
