Is this the correct usage of verb form etc?

Question

En 1948, Neruda se escapó de un persecucion politica.

Thanks, T.

Answer 1

I would say 'de la persecución' instead of 'un'

Answer 2

The verb is used correctly. Persecución needs an accent and is a feminine noun, but I would have said la instead of una. Oh, and política needs an accent, too.
