'I'd kill for Islam': your reaction to one man's views
The government says they are increasingly worried about the number of young British men and women travelling to the Middle East to fight with the militant group Islamic State.
Police estimate around 500 have left the UK in the past three years.
Newsbeat spoke with Karim while he was on his way to the job centre in East London. He says being Muslim "makes life better" and his faith comes before everything else. He said "if push comes to shove I would definitely go" fight with IS.
After we broadcast the interview, we had a huge reaction from listeners. One said "it angers me and scares me at the same time".
