bahraini

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for bahraini that I've seen before include "Middle-Easterner" , "Middle East person" , "Native of one Gulf state" , "from middle eastern state" .)

I've seen this clue in The Hindu.
