As the Sydney siege memorial grows, a Muslim bride has made a pilgrimage to Martin Place on her wedding day.

Manal Kassem was adorned in a white dress, hijab and veil when she laid her wedding bouquet on the river of floral tributes to the fatal Lindt cafe siege victims.

After watching the wedding party approach, the city crowd broke into applause.

The 23-year-old bride had chosen the city for her wedding photoshoot, but was hesitant after the siege, says her wedding planner.
