‘Wake-up’: Concern for Muslim community amidGovt decision
The Federation of Islamic Associations of New Zealand (FIANZ) say they are closely monitoring the unfolding situation in Auckland.
They are concerned about the welfare, wellbeing, and the trauma experienced by these students.
The national Muslim umbrella organisation says “the Government has defunded, deprioritised and dismantled many of the key national security framework components”.
The “decision to withdraw these funds is a retrograde step, taken without consideration for the safety and security of New Zealanders and without any consultation with vulnerable communities.”
FIANZ says talk about the reintroduction of military-style semi-automatic firearms implemented after the March 15 terror attack has “emboldened would-be terrorists to discuss shooting Muslim children at schools in New Zealand.”
“This should serve as a wake-up call for the Rt Hon Prime Minister that his Associate Minister for Justice is jeopardising the safety of all New Zealanders, disregarding national security.”
They say these threats could well have been a threat to a synagogue, church, community centre, women’s refuge, or even a shopping centre.
