The Secretary-General of the United Nations Antonio Guterres on Tuesday visited the sites of the Christchurch mosque shootings that claimed 51 lives in March.

Guterres placed flowers at the Al Noor Mosque and Linwood Islamic Centre where the lone assailant had gunned down 42 and nine of his victims respectively.

"We must all show solidarity in response to this dangerous upsurge in hatred," said Guterres who was surrounded by the family members of the victims.

He also underlined two sets of initiatives to prevent similar incident in the future, namely "to protect holy sites and to address hate speech."

Guterres, who is on a three-day visit to New Zealand, will address the Pacific Islands Forum in Fiji on Wednesday.
