Arab Knesset Members Muhammed Barakeh and Ahmed Tibi met with Yasser Arafat in Ramallah today in a show of support for the PLO leader. Following the meeting, the two MK’s incited a riot at the nearby IDF A-Ram checkpoint on the northern border of the capital. Soldiers manning the roadblock say that MK Tibi spat at them and cursed them, and then incited Arabs there to a violent riot. Security forces dispersed the mob by firing their weapons in the air. Police and the army are investigating the incident. In September, 1987, Dr. Tibi was dismissed from the Hadassah hospital medical staff for striking a guard at the hospital entrance.
