WELLINGTON, New Zealand (AP) — New Zealand on Saturday marked the second anniversary of one of its most traumatic days, when 51 worshippers were killed at two Christchurch mosques by a gunman.

Several hundred people gathered at the Christchurch Arena for the remembrance service, which was also livestreamed. A similar service planned for last year was canceled at short notice due to the sudden spread of the coronavirus.

Kiran Munir, whose husband Haroon Mahmood was killed in the attacks, told the crowd she had lost the love of her life and her soulmate. She said her husband was a loving father of their two children. He’d just finished a doctoral degree and was looking forward to his graduation ceremony when she last saw his smiling face.

“Little did I know that the next time I would see him the body and soul would not be together,” she said. “Little did I know that the darkest day in New Zealand’s history had dawned. That day my heart broke into a thousand pieces, just like the hearts of the 50 other families.”

Temel Atacocugu, who survived being shot nine times during the attack on the Al Noor mosque, said the slaughter was caused by racism and ignorance.

“They were attacks on all of humanity,” he said.

He said the survivors would never be able to erase the pain in their hearts and would never be the same.

“However, the future is in our hands,” he said. “We will go on and we will be positive together.”

In the March 15, 2019, attacks, Australian Brenton Tarrant killed 44 people at the Al Noor mosque during Friday prayers before driving to the Linwood mosque, where he killed seven more.

Last year Tarrant, 30, pleaded guilty to 51 counts of murder, 40 counts of attempted murder and one count of terrorism, He was sentenced to life in prison without the possibility of parole.

After the attacks, New Zealand quickly passed new laws banning the deadliest types of semiautomatic weapons.

During the service, the names of each of the 51 people who were killed were read out. The efforts of first responders, including police and medics, were also acknowledged.

Prime Minister Jacinda Ardern told the crowd that when preparing her speech, she had been at a loss for what to say because words would never change what happened.

“But while words cannot perform miracles, they do have the power to heal,” she said.

The Muslim community had experienced hatred and racism even before the attacks, she said, and words should be used for change.

“There will be an unquestionable legacy from March 15,” Ardern said. “Much of it will be heartbreaking. But it is never too early or too late for the legacy to be a more inclusive nation.”
