TEL AVIV — During Tel Aviv's protests last night, a man read out a letter outlining his discontents, doused himself with fuel and set himself alight. The man, Moshe Silman, 57, of Haifa, who was well known in the activist community, is in a medically induced coma with burns on 94 percent of his body. Doctors announced today that he has "low chances" of survival, and in an irony many have struggled to describe, a shortage of burn unit beds is keeping him for now, many hours after the self-immolation, in a standard ER. The lack of hospital beds was one of the protest movement's earliest grievances.
