"The seemingly well-coordinated and decisive action of EU Member States to reduce irregular entries to the EU results in people being expelled back to Bosnia and Herzegovina, where they have no alternative but to stay in squalid and unsafe temporary camps and without effective access to asylum", the report said.
According to the report, the European Union failed to provide adequate support and protection for the refugees entering its borders, effectively revealing a major flaw in its asylum policies.
In addition, the European Union's tightening border security policies that aimed at restricting immigration were "in violation of international and EU law," the report said.
Amnesty International also urged European governments to halt the expulsions of refugees in order to avoid a humanitarian crisis that could mount from the increasing numbers of refugees being sent to Bosnia and Herzegovina and forced to live in unsanitary conditions.
Over 25,530 detected refugees, asylum-seekers and migrants have passed through Bosnia and Herzegovina since January 2018, according to a February report by European Commission's Directorate for EU Civil Protection. An estimated 5,400 are still in-country.
The country has become a major transit route, through which refugees arriving from countries like Pakistan, Iran, Syria and Afghanistan seek to enter the European Union.
