A large number of people have attended a vigil in London's Trafalgar Square to pay tribute to those killed in the Christchurch mosque shootings.
Londoners, Kiwis and visitors from all over the globe gathered to remember those who had died at their places of worship in a peace vigil.
They were bearing banners of peace, holding electric candles and bouquets of flowers.
The move comes less than a week after an Australian terrorist, being called a white supremacist, rampaged through two mosques killing 50 people as they prayed, sparking global revulsion and national outrage.
"Every semi-automatic weapon used in the terrorist attack on Friday will be banned in this country," Ardern told a press conference.
