One of the teenagers attacked with acid in Zanzibar tonight thanked supporters for their good wishes.
Katie Gee took to Twitter to say: "Thank you for all your support x".
The student sent the message from Chelsea and Westminster Hospital in London where she and her friend Kirstie Trup, both 18, were receiving treatment for their burns inflicted in an unprovoked attack while they were on a volunteering holiday.
The pair arrived back in the country and were transferred to the capital's regional burns centre.
Their medic, Andy Williams, consultant burns and plastic surgeon said: "We can confirm that Katie and Kirstie have been transferred to our care at Chelsea and Westminster Hospital's burns unit where we're still assessing their injuries. Both girls are well and their families are with them. They will be staying at Chelsea and Westminster Hospital."
A photograph released by the girls' families showed the injuries one of them suffered in the attack. The girl is shown wearing an open striped shirt and a silver necklace. What appear to be acid burns are clearly visible on her chin, neck and upper chest. One of the girl's injuries are much worse than the other's, it was reported, because helpers used dirty water on her burns.
Ms Trup's father, Marc, told the newspaper from the hospital: "One is much worse than the other. One of the girl's injuries will take quite a while."
One of the victims was reportedly immersed in the sea in the aftermath of the attack at Stone Town, a beach resort, and the salt water helped her skin. "That completely altered the result: the salt water and the acid," Mr Trup said. "The other girl panicked, ran around, made her way to a public toilet."
When "they got to medical centre there was no shower," he added. "They were throwing dirty water at her."
Five men are being questioned by police on the Indian Ocean island after the women were attacked by men on a motorbike as they walked along a road on Wednesday night. Mkadam Khamis, regional police commissioner on Zanzibar, told the Daily Telegraph: "There are five people we have, all men, who we are interrogating over this matter this morning. They have not yet been arrested. They are co-operating and answering our questions."
