>> Europe's biggest street party, London's Notting Hill Carnival, now in its 51st year, and host to hundreds of thousands of revelers.>> I was here last year and my sister, and my mum flew in on Thursday, so I said you have to experience it, it's amazing. Australia needs something like this, it's incredible.
>> But the carnival fell silent this year to remember more than 80 people killed in the nearby Greenfield Tower fire in June. Thousands of people dressed up in colorful costumes, most notably in green, to pay tribute to the victims.>> Today's a gorgeous day and obviously, I'm taking part wearing green for Greenfield people, but even down to my shorts.
Are they green as well?>> Some feared that tempers could boil over at the festival over accusations of mismanagement by local authorities. But the community was determined it should be peaceful vigil. Security was also tight in light of recent attacks on pedestrians. Steel barriers and concrete blocks were put in place along the parade's path.
