Authorities issued arrest warrants for four men who appeared in an August 2013 video from Syria in which they targeted effigies of former secret agent Morten Storm, free speech advocate Lars Hedegaard, politician Naser Khader, the imam Ahmed Akkari, former prime minister Anders Fogh Rasmussen, and cartoonist Kurt Westergaard. Two of the men were said to be Danish speakers, and three them may have been killed in Syria. Abu Sa’ad, a Danish suicide bomber, reportedly carried out an attack for the Islamic State of Iraq and the Sham in Mosul, Iraq on May 20. Danish intelligence says that 100 people have left Denmark to fight in Syria, and many have returned, but so far none have been prosecuted. Authorities recently declined to prosecute two other cases involving Danish fighters in Syria, and dropped their investigation of an imam at the Qubo mosque.
