If you can in any way get to EU borders, you won't be turned back unless there's a very serious reason to do so (not having documents is not).
Your situation where it seems like your state is retaliating for your political opinion is one of the possible reasons to grant international protection. If it's Russia you're talking about, many people like you already went through the process in Czech Republic.
