Milos Zeman says children, the old and sick deserve compassion but young single men fleeing Middle East should stay behind and take up arms. The Czech president, Milos Zeman, has called the movement of refugees into Europe “an organised invasion” and declared that young men from Syria and Iraq should stay in their countries to “take up arms” against Isis. “I am profoundly convinced that we are facing an organised invasion and not a spontaneous movement of refugees,” said Zeman in his Christmas message to the Czech Republic. Compassion was “possible” for refugees who were old or sick, and for children, he said but not for young men who should be back home fighting against jihadists. “A large majority of the illegal migrants are young men in good health and single. I wonder why these men are not taking up arms to go fight for the freedom of their countries against the Islamic State,” said Zeman. Fleeing their war-torn countries only served to strengthen Isis, he said. The 71-year-old evoked a comparison to the situation of Czechs who left their country when it was under Nazi occupation from 1939 to 1945. It is not the first time Zeman has taken a controversial stance on Europe’s worst migrant crisis since World War II. In November the leftwinger attended an anti-Islam rally in Prague in the company of far-right politicians and a paramilitary unit. The country’s prime minister, Bohuslav Sobotka, who has previously criticised the head of state’s comments, said Zeman’s Christmas message was based “on prejudices and his habitual simplification of things”.
