ITV News understands that one of the suspects in the shooting of schoolgirl Imani Green in Jamaica has himself been shot and killed.
Police in Kingston, Jamaica say it is not clear who carried out the shooting and motive is currently not know.
Anne Wilson, headteacher at Fircroft Primary School, said Imani Green, who suffered from sickle cell anaemia, "coped very well" with her condition which forced her to stay indoors at play time to avoid getting cold.
The school had granted her permission to spend time in Jamaica because the warmth was known to be better for health.
Mrs Wilson told Sky News:
Imani Green's cousin Brandese Brown, who witnessed the attack in Jamaica, told ITV News of the moment she saw "the shot coming out of the gun."
Sandra Fisher, the grandmother of 8-year-old Imani Green who was fatally shot in Jamaica, told ITV News she found the British girl in a "pool of blood."
Ms Fisher added that Imani, who travelled to Jamaica on Boxing Day, was a "very friendly" girl who "made you laugh" and spoke both Jamaican Patois and English.
Eight people have been arrested in connection with the shooting of 8-year-old Imani Green, the British girl who was killed in Jamaica, according to the BBC.
Deputy Supt Steve Brown said the eight were being questioned following their arrests, the website reports.
Jamaica's security minister, Peter Bunting, has condemned the killing of 8-year old British girl Imani Green.
He told the Jamaica Gleaner newspaper: "The senseless killing of a young, innocent child must outrage all well-thinking Jamaicans, and cause us to join our security forces in an intensified effort to rid our communities of criminals."
Anne Wilson, head teacher of Fircroft Primary School in Tooting, has paid tribute to pupil Imani Green, who was shot dead in Jamaica during a family visit to the country.
She said: "The entire Fircroft School community is deeply shocked and saddened by the tragic news of the death of our pupil Imani Green. Our thoughts and prayers are with her family to whom we pledge our continuing love and support.
“Imani was a happy, playful child who was popular with staff and pupils alike. She suffered from sickle cell anaemia and we had to take great care to protect her from the cold, which could adversely and dramatically worsen her condition.
"She dealt with her illness very bravely and coped well with the special arrangements we had to have in place to support her.
"She had been given special permission to travel to Jamaica so that she could benefit from the warmer climate and we had been in contact with the local primary school she was attending whilst there to make sure she was receiving an appropriate education.
“We are now in the process of contacting all the families of children in the same year group to break this terrible news to them and we will be taking steps to offer support and counselling to all those children and staff who are affected by this terrible tragedy.”
An eight-old British girl has been shot dead while on holiday in Jamaica.
Imani Green, from London, was hit twice at a cafe owned by her cousin on the island's north coast.
Police said a gunman entered and opened fire following an argument. They believe it may have been a revenge shooting following an earlier attack.
