Little Green Footballs reports that:
A barrage of Katyusha rockets has been launched at northern Israel, and for the first time one has reached the city of Haifa.
CNN has reported that at least one of the weapons was a long-range ballistic missile (not just a Katyusha rocket), fired by Iranian guards.
If this report is true it represents a clear act of war on the part of Iran. Iranian prime minister Ahmedinejad, out of Muslim solidarity, is threatening Israel with terrible consequences if they attack Syria, but it looks as if the Iranians may have already overplayed their "solidarity" hand.
