A doctor says a dozen soccer hooligans invaded the delivery room of a Buenos Aires hospital, hoping to avenge the death of a gang member killed in a fight with a rival faction.

Marcelo Struminger, president of the doctor's association at Santojanni Hospital, said Thursday gang members associated with the Argentina club Nueva Chicago raced through the delivery room and other parts of the hospital on Wednesday. They were looking for a rival hooligan known as ''Aldo The Paraguayan.''

He is believed to have been involved in the death Wednesday of Agustin Rodriguez, who was killed in a fight between his faction, ''Los Perales,'' and the rival faction ''Las Antenas.''

Soccer violence has plagued Argentina for years.
