Danish police are assisting the Swedish authorities in the search for a man suspected of planning a terrorist attack against Sweden, reports DR.

Although there is no specific knowledge about the man’s whereabouts, the Swedish police believe he is hiding somewhere in Scandinavia.

Both PET and the Danish police have received a picture of the man, who has been identified as Mutar Muthanna Majid, an Iraqi estimated to be 25 years old, who allegedly fought for the Islamic State in Syria.

Meanwhile, Rob Wainwright, the head of Europol – the EU’s law enforcement agency – has warned that Europe is facing the “most serious terrorist threat since 09/11” in the wake of the Paris attacks.

According to Wainwright, it is “reasonable to assume – without exaggerating – that more attacks are likely” to happen and Europe faces the most severe terrorist threat of the past 10 years.
