Many important news stories don't get reported by Newsround, or they get reported a long time afterwards. The siege in Sydney is one story which hasn't yet been reported, though of course it did get a lot of coverage on the main TV news channels.

Katrina Dawson, 38, and cafe manager Tori Johnson, 34, both died as heroes.

Katrina Dawson, who was married to Paul Smith, with three children, is reported to have shielded a pregnant friend and colleague Julie Taylor, whom she had been meeting for a coffee.

Tori Johnson was killed as he attempted to wrest the gun from the hostage-taker.

As a gay man living in Australia Tori Johnson was, in effect, a second class citizen without the right to marry afforded to other people in that country. His life partner, who isn't mentioned in this BBC news webpage, was Thomas Zinn. They'd been together for 14 years.
