Europe can't become a new home for millions of refugees, former German Chancellor Helmut Kohl wrote in a preface to the Hungarian edition of his appeal "Out of concern for Europe".

Kohl has criticized the open-door policy of current German Chancellor Angela Merkel toward refugees and expressed his solidarity with Hungarian leader Victor Orban.

"The solution lies in the affected regions, not in Europe. Europe can't be a new home for millions of people in need worldwide," Kohl wrote, cited by German newspaper Tagesspiegel.

The politician questioned Merkel's strategy, stressing that she acted on her own initiative and has not discussed her policy with the EU partners.

"Private decisions, regardless of how justified they may seem to an individual, as well as national initiatives must belong to the past," Kohl argued.

European countries are currently struggling to manage a massive refugee crisis, with hundreds of thousands of people leaving conflict-torn countries in the Middle East and North Africa to ask for asylum in Europe. Many refugees are seeking to arrive in wealthier EU states such as Sweden or Germany.

In his appeal, Kohl also stressed that in addition to humanitarian aspects Europe should take into account its "cultural and security interests".

Many refugees come "from different cultural backgrounds. Many of them profess other than the Judeo-Christian faith, which is one of the foundations of our values and social order," Kohl stated.

The former German Chancellor also supported the policy of his "friend" Viktor Orban who appeals for stricter migration rules and closure of European borders.

In February, Hungary among other European countries along the Balkan route, including
Serbia, Croatia, Slovenia and Austria closed its borders to newcomers. The move has resulted in thousands of refugees being stranded in Greece, particularly along the border with Macedonia.

More than 130,000 asylum seekers – some 13 percent out of all migrants registered in Germany last year - went missing in 2015 after being registered in the country, a local newspaper reported Friday, citing German Interior Ministry data.

More than 130,000 asylum seekers – some 13 percent out of all migrants registered in Germany last year — went missing in 2015 after being registered in the country, a local newspaper reported Friday, citing German Interior Ministry data.

The figures were published by the Sueddeutsche Zeitung newspaper after German opposition party Die Linke made an official request to the interior ministry about the number of refugees who never turned up at the accommodation provided for them.

According to the paper, the ministry said the reason for the migrants’ absence could be either moving on to a different country or "submersion into illegality." Some migrants who have family or friends already living in Germany might have decided to stay with them, instead of living at governmental reception facilities, the media outlet noted.

Amid a major refugee inflow to Europe, German Chancellor Angela Merkel has come under fire for her open-door policy which saw over one million migrants arrive in the country in 2015.

The head of Germany's Federal Office for Migration and Refugees, Frank-Juergen Weise, admitted earlier this week that there are currently up to 400,000 people in the country whose identities are unknown to authorities.
