A Royal Commission report into last year's terror attacks on to Christ church mosques has Bean made public on in it, the report said security agencies were almost exclusively focused on the threat from Islamist terrorism.

It did also conclude, though, that there was no plausible way the gunman could have been detected.

The white supremacist Brenton Tarrant, was sentenced to life in prison for killing 51 Muslim worshipers and injuring dozens of others.

Shaimaa Khalil reports the terrorist attack that shocked the world and devastated New Zealand.

Take your time.

On March the 15th 2019, Brenton Tarrant, a white supremacist, opened fire in two mosques, killing 51 people and wounding dozens more as they got ready for Friday prayers.

The quiet city of Christ Church became the scene of one of the country's darkest days.

More than a year and a half on a Royal Commission report on the mass shooting has now been made public.

Today we have answers on the meadows off how the attack occurred and what could have been done to stop it.

The commission found no failures within any government agencies that would have allowed the terrorists planning and preparation to be detected, but they did identify many lessons to be learned in significant areas that require change.

The report found that security agencies were almost exclusively focused on the threat from Islamic extremism and failed to investigate threats by the far right.

It also said the police did not enforce proper checks on firearms licenses, but it found no failings within government agencies that would have alerted them to the imminent attack.

Representatives off the AL Nor and Linwood mosques said the findings showed that particular government bodies failed to protect the Muslim community.

Ayala Marie, whose brother Hussein was killed after challenging the gunman, welcomed the report but said it brought back raw emotions.

It's still very had to refer Thio Hossein in the past dance, but he was the backbone Thio family and to his circle of friends on DSA society.

He is my hero and he is a hero that society does deserved.

Thio have.

I do hope that there are some leanings, um, not just in New Zealand but to other countries that can implement as well in a very quick, swift men or to mitigate such risk from happening.

Some of the report's recommendations include further changes to hate crime laws, how firearms air managed and the creation of an early intervention police program for individuals showing signs of radicalization.

The aim is to prevent similar attacks and to help New Zealand and Christ Church move forward.

But for those who have lived through the horrors of the day, life will never be the same.
