Four Arabs were arrested last night after they attacked two guards at Jerusalem's Mt. Scopus Hadassah Hospital. Hospital staff received word of many wounded that were to be brought to the hospital, as a result of an explosion in a home in the Arab village of Bir Naballah. The guards therefore asked the Arabs in the emergency room, who had escorted a friend to the hospital, to leave and make room for the others. The Arabs refused, attacked the guards with sticks and caused damage to equipment in the emergency room. Two of them were arrested on the spot, and two others were apprehended after they tried to escape.
