What are those persian texts on CS series?

I have been playing Counter Strike series since I was a child. I was used to play the cracked version of CS 1.6 and the CS Source which I had downloaded from Iranian websites. So I thought the Iranian version had added those text to the maps but now I have bought the original CS GO from Steam then I saw some Persian texts on map again. What are they supposed to mean?
There many Arabic texts on DUST2 because it refers to Plastine but it was very strange to me that a Persian text was there too. Why would be there a Persian sentence on terrorist base?
