MK Michael Kleiner (Herut) has called for Arab MK Ahmed Tibi\'s citizenship to be revoked, while MK Eliezer Cohen (National Union-Yisrael Beiteinu) sufficed with demanding that his Parliamentary immunity be removed. The calls were prompted by Tibi\'s solidarity visit to Yasser Arafat in Ramallah yesterday, during which Tibi referred to the \"aggressions against the Palestinians by Israel.\" Cohen is urging speedy legislation of his bill stipulating that the immunity of MKs who make calls that can be interpreted as supporting terrorism be immediately removed. When Arafat began his speech yesterday and called for \"one million martyrs to march on Jerusalem,\" Tibi\'s supporters chanted, \"To Jerusalem we march, millions of shahids [holy martyrs].\" Tibi himself did not take part in the chanting. Kleiner said that if the Israeli-Arab citizens who accompanied Tibi are found to be members of Tibi\'s political party, \"the party should be outlawed and declared a terror organization.\"
