Poland's education minister has accused former Polish ambassadors of "high treason" after they were critical of the government's treatment of migrants on the Polish-Belarusian border. The Conference of Ambassadors of the Republic of Poland published on Wednesday a statement on the website Onet.pl, saying that "the situation on the border with Belarus is a disgrace for Poland, which is beginning to fulfil the criteria of a crime against humanity." Przemyslaw Czarnek attacked the statement's authors saying they "are people who absolutely do not represent the interests of the Polish state and nation".
