“The Kingdom of Saudi Arabia denounces all types of terrorism,” a ministry statement said, citing an official source.
The source reiterated the importance of respecting religions, and extended condolences to the families of victims and the government and people of New Zealand.
The statement also wished the wounded a speedy recovery.
The Saudi Embassy in New Zealand said that a Saudi citizen was slightly wounded in the mass shooting at two mosques in Christchurch.
Political and Islamic leaders in the Arab world expressed their disgust at the deadly shooting.
Among those condemning the attack was Anwar Gargash, the UAE’s minister of state for foreign affairs.
He tweeted “heartfelt condolences” to New Zealand.
Gargash wrote: “Our collective work against violence & hate must continue with renewed vigor. Our thoughts & prayers are with the families of the victims.”
In a statement, Egypt’s Al-Azhar University said the attacks had “violated the sanctity of the houses of God”.
“We warn the attack is a dangerous indicator of the dire consequences of escalating hate speech, xenophobia, and the spread of Islamophobia.”
More had to be done to promote the co-existence of different religions and cultures, the university said.
