"Yisrael Beiteinu" chief MK Avigdor Lieberman said Friday that Arab Knesset members bore responsibility for the murderous attack in Jerusalem. "Those who call IDF activity for the protection of the residents of the south 'war crimes,' and who incite and burn the Israeli flag in Umm El-Fahm, cannot absolve themselves of responsibility for the heinous attack in Jerusalem," Lieberman said.

"One cannot disconnect yesterday's terror attack from the incitement by the Arab Knesset members, which we hear daily in the Knesset," Lieberman explained. "They are not just a fifth column, but official representatives of terror organizations in Israel's Knesset."

Lieberman said that the fact that the terrorist carried a blue ID card was not surprising, "if one takes into account the incitement of Israel's Arabs."
