Two Islamic terrorists stayed at German refugee camp after landing on Greek Island and traveling through Austria. Some terrorists have faked their own deaths to make it easier to return to Europe-CNN

4/8/16, "Immense challenges remain despite arrests of terror suspects," CNN, by Paul Cruickshank and Tim Lister

"Additionally, there will be concern that Krayem, a Swedish jihadist who had been to Syria, managed to slip into Belgium unnoticed -- as had another senior figure in the Paris/Brussels cell, Mohamed Belkaid. Belkaid was shot dead in a police raid days before the Brussels attacks.

Krayem, a resident of Malmo, was on the radar screen of Swedish intelligence services, according to Magnus Ranstorp, a counterterrorism expert at the Swedish National Defense College....

But then he managed to get back into Europe undetected. Investigators now believe that 

along with a man using the name Monir Ahmed Alaaj, Krayem reached the Greek island of Leros in September. They traveled through Austria to a refugee camp in Ulm, Germany. 

On October 3, Abdeslam collected Krayem and Alaaj at an Ibis hotel near the refugee center in Ulm and drove them to Brussels, investigators said. German investigators believe Abdeslam also picked up a third (unidentified) man.

Alaaj was arrested with Abdeslam in Molenbeek on March 18, days after their hiding place in the Forest district of Brussels was discovered by police....

There is concern among European intelligence officials that ISIS operatives have been faking their own deaths to make it easier to return to Europe

to carry out attacks. It was a trick used by Abaaoud in autumn 2014, shortly before he slipped into Greece to coordinate the Verviers plot.

Another man due to be tried in absentia for the Verviers plot is Noureddine Abraimi, Belgium's national news agency reported. He, too, is on the security bulletin circulated among European law enforcement agencies in connection with the Paris attacks....

The Belgian courts are getting used to trying terror suspects even if their whereabouts unknown. The first major trial in Belgium related to jihadi travel to Syria involved 45 defendants but only seven were in court.

In another trial in July -- of people associated with Zerkani --14 were tried in absentia. Two have since been killed. Another, Reda Kriket, was arrested in France last month. But 11, all of whom have international arrest warrants, remain at large.

The complexity of the legal process, often involving more than a dozen defendants in terror cases, also means that trials are slow to open. The Verviers raid was almost 15 months ago. The federal prosecutor hopes the trial of those alleged to have been involved will open this month, but the defense wants it delayed until the fall."...
