He says that he came to Syria because he saw similarities between what was happening there and the Bosnian war. When asked about rebels who tortured a prisoner to death in a particularly gruesome way, he brushed that aside by saying that Syria is worse.
Janovic adds, "We came to establish the rule of God on earth. Our goal here does not stop, [after Assad is defeated.] We will aim towards Jerusalem. We want to fight the Jews.
"We are Muslims. We want to save mankind from villains and their evil. So we know why we came from and the future road waiting for us. ... We came to fight Israel and and eliminate them."

His actual name is Bajro Ikanovic. He was part of a local support-cell of Bosniaks who procured explosives and weapons for two Muslims from Scandinavia, who were taken in Sarajevo in 2006 while preparing a suicide bomb attack. Another person in the support cell, Senad Hasanovic, has also turned up in Syria after getting out of jail.
Bajro Ikanovic was wounded in battle in May, according to the Balkan press.
The two terrorists from Scandinavia were Mirsad Bektasevic and Abdulkadir Cesur. Their arrests in Sarajevo touched off a wave of arrests in other countries among the terrorists they were in contact with - the so-called Glostrup terror case in Denmark, Irhabi007 ("al Qaedas webmaster", a Moroccan named Younis Tsouli) and two companions in Great Britain, two islamists from Atlanta in the US, and a larger group in Canada, that had begun procuring fertilizer for three car bombs.
