Underground Fighters Free 251 Arabs, Jews from Palestine Prison; New Communist Victories in China

JERUSALEM, May 4--Jewish underground fighters freed 251 Jewish and Arab prisoners of grim Acre prison today by blasting a hole in one of its centuries-old walls, as 15 persons died in the bloodiest outbreak of violence in the Holy Land in many weeks.

Ten men, including four Jewish prisoners, an Arab prisoner and three Jewish raiders, were killed in the wholesale prison delivery which the underground fighter accomplished by planting four bombs in Turkish baths adjoining the prison wall after screening the attack with gunfire and grenade blasts.

Two other Jews who apparently were wounded fatally in the raid were found dead in a jeep near Acre.
