Acid victims' families urge action
The families of two British women targeted in an acid attack in Zanzibar spoke of their frustration that the attackers have not been brought to justice.
Londoners Kirstie Trup and Katie Gee, both 18, are recovering after being targeted by two men on a moped during a volunteering holiday on August 7.
Their families called on the UK government to apply more pressure on the Tanzanian authorities.
Doug Morris, the partner of Miss Gee's mother, told the BBC's Radio 4 Today programme: "If the Foreign and Commonwealth Office are as committed to helping to bring these people to justice on behalf of two British citizens, then you would expect them to move hell and high water to do that.
"And there just doesn't seem to be any sense of urgency to conclude matters."
There is still confusion over how to get a photograph of a suspect to the women for identification, according to Miss Trup's father Marc.
He said: "The photograph cannot be sent in the correct format that is acceptable by Interpol, or the British authorities, and as a consequence of that nobody has seen the photo."
The teenagers, from north London, were nearing the end of a month-long stint teaching English when they were attacked.
Miss Trup suffered severe chemical burns to her shoulder and back from the sulphuric acid which was launched at the pair as they walked back from a restaurant on the predominantly Muslim island.
Police in Zanzibar have interviewed several people, including eyewitnesses, and are believed to have identified a possible culprit.
Mr Trup told Today: "I'm particularly upset with the Tanzanian authorities. I think they just hope this will go away. The Foreign Office do send us emails, but the emails say the same every single time and they seem to imply that the British Foreign Office has clout, it has a voice, but clearly none of that is working because we are not getting any progress whatsoever.
"I suspect the Tanzanian authorities don't take the Foreign Office remotely seriously. We want the judicial system to work properly.
"I would like to see whoever threw that acid brought to justice. I don't blame the country, I don't blame the religion. I blame the person. He needs to be brought to justice.
"Above all, the girls want to know why he did it and we would like to know why he did it. Was it racial, was it a religious thing? We have no idea why this person did it."
Mr Morris said: "If they mean what they say, if it's important for them to find the perpetrators of this attack, this crime, and bring them to justice - as they said at the time - then they should be assisting us in every way that they possibly can.
"Everybody is trying to sort of give the impression that they are dealing with this, and we are served platitudes on a bi-weekly basis.
"This crime can't go unpunished, for the girls' sake as much as anything else. What sort of message is that, that you can do something horrific, you can do something horrible, and you can get away with it?
"We don't want it to drag on and on, we want justice done and we want justice done now."
The families said they had "no idea" why the girls were targeted, as they were behaving respectfully and dressed in accordance with local customs.
Mr Trup said his daughter was now recovering from her injuries: "Kirstie is doing well, she's moved to university. She seems to be progressing well mentally and physically. Kirstie is still having treatment at the local hospital. She has to wear a pressure garment over her burns, which she has to wear 23 hours a day for one whole year.
"She goes regularly once a week to hospital for continual physiotherapy on her burns, but she's progressing well physically and mentally she appears to be moving well. She has difficult times."
Mr Morris said: "Katie is remarkable. She's very strong mentally and just coping with the process of healing."
