Bulgaria and Romania have partially joined Europe’s Schengen area of free movement.
Despite the partial membership, the two countries’ air and sea borders has lifted its controls.
Created in 1985, the Schengen area allows more than 400 million people in the European Union to travel freely without internal border controls.
As partial members, the Schengen zone now comprises 29 members – 25 of the 27 EU member states as well as Switzerland, Norway, Iceland and Liechtenstein.
