Iranians calling to assassinate Mubarak

This goes a little beyond "regime change..."

From MEMRI:

Iran's attacks and accusations against Egypt and Saudi Arabia have recently intensified. In early December, Iran's leading conservative government dailies Kayhan and Jomhouri-ye Eslami accused the Egyptian and Saudi regimes of treason, and called on their peoples to topple their regimes. Kayhan editor Hossein Shariatmadari, who is close to Supreme Leader Ali Khamenei, praised Khaled Islambouli, the assassin of the late Egyptian president Anwar Al-Sadat, and called to follow his example. At the same time, student demonstrations were held in Tehran, during which protesters called for killing Egyptian President Hosni Mubarak and threw firebombs at the Egyptian interest office.

Kayhan editor Shari'atmadari wrote in Kayhan's December 2, 2008 editorial: "...The absence of [Sadat's assassin] the martyr Khaled Islambouli, God bless his soul, is sorely felt. Many more should follow his example. "

And, since a picture is worth a thousand words, here is a sign from an anti-Egypt rally from Iran's FARS news agency:
Not much subtle about that.
