German authorities expect up to 1.5 million asylum-seekers to arrive in Germany this year, according to an internal official report, cited in Germany's top-selling Bild newspaper. These estimates are almost twice the previous official figures.
The authorities are now predicting to accept 920,000 refugees in the next three months, which would bring the total number of refugees to 1.5 million by end of this year, Bild reported.
German officials have not confirmed the new estimates yet, however, German Interior Ministry spokesman Harald Neymanns said that "we are still expecting the migration pressure to drop in the winter months."
Previously, the German government speculated the number of refugees this year to be 800,000 to one million in total.
"The significant number of asylum-seekers risks becoming an extreme burden for the regions and communes," the report added.
Over 4 million Syrians fled the country following the escalation of the Syrian Civil War in 2012. Another 7.6 million are displaced within the country.
Thousands of Syrian refugees have been marching towards western European countries, using a route through Greece-Macedonia-Serbia-Hungary-Austria, from east to west, forcing the 28-member bloc to face its worst refugee crisis in decades.
One of their most preferred destinations is neighbouring Turkey, which hosts the most Syrian refugees in the world, with around 2 million according to registration records of the United Nations.
