SYDNEY (Reuters) - One of four people detained in New Zealand after mass shootings at two mosques in Christchurch is Australian, Australian Prime Minister Scott Morrison said on Friday.

“I can confirm that the individual who was taken into custody I have been advised is an Australian-born citizen,” he told reporters in Sydney.

“As family members with our New Zealand cousins today, we grieve, we are shocked, we are appalled, we are outraged, and we stand here and condemn absolutely the attack that occurred today by an extremist, right-wing, violent terrorist.”

New Zealand media have reported that between nine and 27 people were killed in the shootings.
