Four children and a teacher have been killed in Brazil after a security guard threw flammable liquid on them and set them on fire, officials say.
The man also set himself alight at the childcare centre in the remote town of Janauba in Minas Gerais state.
Video footage showed chaotic scenes outside, as parents cried and panicked as the news broke.
Twenty-five people, mostly children aged four and five, are being treated for burns in local hospitals.
Some of the patients may still need to be airlifted to a specialised burns unit in the state capital, Belo Horizonte.
The security guard has been identified by police as Damiao Soares dos Santos, 50. He died in hospital of his wounds.
The reasons for the attack are still being investigated.
Local media has reported that he was dismissed after returning from annual leave last month with an alleged health condition.
He went to the Gente Inocente childcare centre to hand in his medical certificate and then started the fire, O Globo newspaper reported.
A Brazilian nursery school guard burned six small children and a teacher to death after spraying them with alcohol and setting them alight on Thursday in an attack which has horrified the nation, said emergency services.
Dozens of people were also hurt in the blaze while the guard, who was reported to be mentally ill, died after succumbing to his own burn injuries.
The tragedy occurred in a modest quarter of Janauba, a city of 70,000 about 600km (370 miles) north of Belo Horizonte.
The nursery school was called "Innocent People."
The initial death toll of four rose to six when two badly burned children died, according to news reports which quoted fire officials.
