The threat comes after the famous search engine left the body of water between Iran and the Arabian Peninsula unlabeled on its online map service. However, if you search for "Persian Gulf" in Google Maps, the search engine displays the body of water, just not its name.
Foreign Ministry spokesman Ramin Mehmanparast says that if Google does not restore the name of the Persian Gulf, it will face "serious damages."
Mehmanparast told the semiofficial Mehr news agency Thursday that Tehran has already warned Google of possible legal action.
Iranians are highly sensitive about the name of the body of water, which has historically and internationally been known as the Persian Gulf.
Some Arab states insist on calling it the Arabian Gulf.
