"Objectively assessing the situation, it is difficult to believe that by the end of the next year the whole European Union and particularly Estonia will manage to resettle the planned number of people," Pevkur said, as quoted by Sputnik Estonia.
Under the quota scheme Estonia must accept about 550 refugees by 2017. The country has accepted only 60 people so far, which has triggered concerns of the EU authorities.
The European Union is currently struggling to manage a massive refugee crisis, with hundreds of thousands of people fleeing conflict-torn countries in the Middle East and North Africa. The EU border agency Frontex recorded more than 1.8 million illegal border crossings into the bloc in 2015.
