Many of those trying to enter Poland via Belarus have begun their journey in Istanbul, Turkey.
There are travel agencies that advertise flights to Minsk, but also a more hidden activity that tries to help migrants enter the EU.
Mahmoud, who is actually called something else, is a member of a smuggling network that offers migrants help into Europe.
He does not think that he or his network bears any responsibility for the migrants who have been harmed at the Poland-Belarus border.
- No one has any responsibility.
Everyone who travels that road knows what applies.
You know the obstacles that exist, and death is everywhere on earth.
