Hundreds attended a vigil held in central London's Trafalgar Square on Thursday evening (March 21), standing in solidarity with New Zealand following the terror attack on a mosque in Christchurch last week.

The vigil included a call to prayer, two minutes silence, New Zealand's national anthem (sung in Maori and English) and an emotional waiata (Maori song) and a rousing haka lead by the Ngāti Rānana London Māori Club.

New Zealand's Prime Minister said reforms to the country's gun laws are underway in the wake of the attacks.

A 28-year-old Australian man has been charged with murder in relation to the incidents, which killed 50 and injured dozens more.
