More than 170,000 migrants and refugees from the Middle East, Asia and Africa have crossed Slovenia since mid-October when Hungary closed its southern border with Croatia diverting the flow towards Slovenia. Around 30,000 more are expected to arrive in Slovenia over the next few days.
"In the coming days we will start putting up temporary technical hurdles on the border to direct the flow of migrants," Cerar told a news conference, adding: "We are not closing the border. We want to ensure a controlled and secure flow of migrants and prevent a humanitarian catastrophe."
