A gunman has opened fire at a school in Brazil, killing at least 12 of its pupils.
A suicide note was left by the attacker, named as ex-student Wellington Menezes de Oliveira. Having reportedly told staff at the school in Rio de Janeiro that he was there to make a speech, he began shooting, then killed himself as police moved in.
Brazil has called this an unprecedented tragedy.
More than 20 other people were hurt in the attack. A football pitch nearby was used by helicopters taking injured children to hospital.
President Dilma Rousseff struggled to contain her emotions as she called for a moment of silence to honour the youngsters whose lives were cut short.
