A Muslim bride's tribute to those killed by a lone wolf attacker in Sydney last week has gone viral after she interrupted the most important day of her life to lay a bouquet of flowers in Martin Place.

Manal Kassem paid respects to the slain hostages Katrina Dawson and Tori Johnson after they were shot dead by the religious cleric Man Haron Monis in the Lindt Cafe situated in Martin Place after a 15-hour stand-off with Australian authorities.

"She was going to cancel [the photoshoot] because she didn't want to be judged – celebrating her wedding in a scarf while people were terrorised.

"But she made it her priority to visit the memorial site as the first pit stop.

"She did it out of respect for her country that will one day be the country of her children and grandchildren."

Dawson was having a cup of coffee with one of her colleagues at the Lindt cafe when Monis entered the shop and took 17 staff and customers hostage.

Tori Johnson, 34, the manager of the Lindt Chocolat Café in Martin Place was also killed alongside Dawson in the final stages of the 16-hour ordeal, when he allegedly attempted to snatch the attacker's shotgun.

Dawson has been lauded as a hero following reports that she was killed as she was shielding her pregnant friend from gun shots.
