The Australian prime minister, Tony Abbott, confirmed reports that an Australian-Colombian man was among the dead. Social media named him as business analyst Javier Camelo, a 28-year-old from the Waterloo area of Sydney, who also held Colombian citizenship.

Camelo, who reportedly worked for American Express in Sydney, was killed along with his mother, who was named as Miriam Martínez.

Camelo, a former student at the University of Sydney, graduated this year with an MBA from Spain’s IE Business School.
