TEHRAN - The Saudi embassy in Tehran in a letter had asked the kingdom's officials to foment unrest in Iran by investing huge sums in social networks and media, shows a cable released by the Yemen Cyber Army after it hacked the Saudi Foreign Ministry in May.

The document shows that the Saudi ambassador in Tehran in a cable to Riyadh called for conducting measures to stir unrest in Iran and pave the way for changing the country's political system, Fars reported Saturday.

The Saudi envoy also underlines in the cable that the problems of Iran's political system should be highlighted through media outlets and social networks such as Twitter and Facebook.

The Saudi diplomat then calls for using the Persian and Arabic-language media and the Arabic-speaking citizens of southern and western Iran for the same purpose.
