A 20-year-old German tourist who lost an arm in a shark attack off the coast of Maui in Hawaii last week has died of her wounds.
Jana Lutteropp had been hospitalised since she was attacked while snorkelling near Maui and had been on life support, a hospital spokeswoman said.
Ms Lutteropp was snorkelling in an area known as White Rock last Wednesday when the attack occurred.
Four days after that attack, a 2.4m shark bit a 16-year-old boy in the legs while he was surfing along the east coast of Hawaii's Big Island.
He suffered 30 deep lacerations in the attack, which occurred while he was surfing with friends at Pohoiki Bay, but he is expected to fully recover.
That incident marked the ninth shark attack on a person in Hawaiian waters this year, according to William Aila, chairman of the state Department of Land and Natural Resources.
Mr Aila said Hawaii typically documents five or six close encounters between people and sharks every year, including bites or cases in which a shark may bump into or brush up against someone.
According to the Land and Natural Resources department, the last fatal shark attack in Hawaii took place on 7 April 2004, when a surfer suffered severe bite wounds off the Maui coast.
