Exiles of all nationalities passing through Istanbul are not found in the center of the city.
A tragic event gives some information about it: five Indians exiled were killed in a fire at a building near the international airport. Releases from the police during raids or accidents of this type give a few bits of information. Exiles in transit are often hidden in apartments or various buildings on the outskirts of the city waiting to go to the border.
It is therefore impossible to contact them.
