Washington - A fifth girl died Tuesday of injuries received during the previous day's school shooting in a Pennsylvania Amish community, US media reports said.
Three girls died instantly and another seven were brought to hospital with critical injuries after a gunman walked into the school on Monday and carried out his attack. Two of the seven died Tuesday morning, US media reported.
The five dead are four students and a teaching assistant.
The 32-year-old gunman, who was not himself a member of the Amish religious sect, barricaded himself into the one-room school and ordered the boys out before carrying out the attacks execution-style and then killing himself.
The wounded, some with injuries to the head, were airlifted to special regional hospitals across two states following the tragedy.
The shooter, Charles Carl Roberts IV, 32, a milk tanker driver, told his wife by mobile phone shortly before pulling the trigger that he was exacting revenge for something that happened when he was a child.
The Amish religious sect, originally from Germany and Switzerland, settled in southeastern Pennsylvania 200 years ago in search of religious freedom.
The violent events at the school marked the third US school shooting in less than a week.
Last week, a gunman killed a high school girl at a Colorado high school after sexually assaulting six girls, and a student killed a principal in a small Wisconsin town.
