New Zealand Muslims were brought to tears by a social media display of solidarity in Sydney during the Lindt cafe siege.
Sydneysiders, fearing anti-Islam acts against Muslims in religious dress, took to social media to offer support.
What started with one woman offering support with the Twitter hashtag #illridewithyou quickly became a citywide and then global trend, generating about 120,000 tweets.
Tessa Kum, a Sydney television content editor, told Guardian Australia she started the hashtag after reading about another Twitter user's kind act.
Rachel Jacobs had tweeted that a Muslim woman on the train with her had removed her hijab, presumably out of fear.
