Yigal Yehoshua, 56, was seriously injured Tuesday night when a flying rock caught him in the head during an Arab mob riot in Lod. On Monday he died in hospital. His family has decided to donate his organs for lifesaving transplants. His killers have not been caught. Yigal Yehoshua was the first Jewish fatality in the wave of violent Arab Israeli disturbances sweeping mixed towns for more than a week. Several attempted lynches were thwarted.
