Prague (Jul. 20)
The self -styled “Defenders of Arab Palestine” who have sent threatening letters during the past week to Jewish organizations in Italy and England and who claimed responsibility for the blowing up of the Panamanian vessel Vrissi in Genoa harbor on July 11th, have extended their activities to France and Czechoslovakia.
The office of the Jewish Agency here received a letter from this group threatening its officials with murder unless they suspend their activities, presumably assistance to Palestine-bound immigrants. The letter was mailed from Paris.
