According to Dagbladet, the first group of terrorists have already arrived in Europe and have gone underground. The second group recently completed training in a military camp, but is still in Syria.
The information was given to the newspaper from a source familiar with the situation under a condition of anonymity. The Norwegian Police Security Service (PST) confirmed to Dagbladet that it has this information as well.
"PST knows about it. [But] I do not want to go into details about the information that is available to PST," PR-Head of PST, Trond Hugubakken said.
The source also told Dagbladet that the first group of trained terrorists originally consisted of 300 people, but 28 of them were killed in Syria, in bombings and shootings. 272 militants arrived in Europe and then received the command to go into hiding.
The second group consisted of 150 terrorist fighters who are still in Syria. 112 of them have already completed their training in Iraq and have arrived in the Syrian city of Raqqa about two weeks ago, the source said.
According to Hugubakken, there is a huge number of reports about terrorists right now, some of which are based on true information, but additionally, many are false.
