Radical Islamists are languishing in German jails because their North and West African homelands have stricter re-entry laws than the European powerhouse. Germany accepted more than one million migrants, asylum seekers and refugees under Angela Merkel’s open door policy, but is now unable to deport up to 224 identified terror suspects because they do not have adequate paperwork identifying their point of origin.

There are currently 80 extremists in German prisons, with 144 others still at large. Germany’s domestic intelligence agency, the Office for the Protection of the Constitution, believe all the suspects have the potential to carry out terror attacks.

GETTY The Berlin terrorist, Anis Amri, was known to authorities and attended more than 20 German mosques

A wave of extremists was identified by authorities after the deadly Berlin Christmas market attack, carried out by Tunisian-born Anis Amri. The warped terrorist ploughed a truck into the market, killing 12 people as well as the Polish driver, and injuring 50 more.

Amri was known to authorities and had contact with radicals at more than 20 mosques across the country, according to intelligence agencies. The DIK Mosque, in Hildesheim, was identified as one of Amri’s main haunts and is known to German authorities as a hotbed of Salafist teaching – a radical, hardline branch of Islam.
