(AFP) – A British backpacker hailed as a hero after being stabbed in an attack at an Australian hostel in which a fellow Briton was killed has died of his injuries, police said on Tuesday. Tom Jackson, 30, sustained critical head injuries in the attack in a rural town in the north of Queensland state last Tuesday. A Frenchman has been in custody since the attack and is expected to be charged with a second count of murder. Mia Ayliffe-Chung, 21, died from multiple stab wounds while a 46-year-old Australian man suffered non-life threatening wounds. “Police can confirm 30-year-old British man Thomas Jackson, critically injured in an alleged knife attack at Home Hill on August 23, has today passed away in the Townsville Hospital,” the authorities said in a statement. “Detectives will upgrade a charge of attempted murder against a 29-year-old man at his next appearance in Townsville Magistrates Court on October 28.” Frenchman Smail Ayad has been charged with the murder of Ayliffe-Chung and is also facing one count of attempted murder regarding the Australian man. Jackson was hailed as a hero by police, who said his actions to help Ayliffe-Chung were “completely selfless”. His father, Les Jackson, flew
