Emergency services and deputies say thoughts lie with Christchurch after mass shootings

At least another 48 people have been wounded.

New Zealand Prime Minister Jacinda Ardern said the attack was well planned, adding that the events in the city of Christchurch represented an extraordinary and unprecedented act of violence.

Local authorities and politicians have taken to social media to show support for the British Commonwealth country.

Guernsey Police tweeted a comment which said: 'We are saddened and appalled to hear of the terrible tragedy which has occurred in Christchurch, New Zealand. Our thoughts are with the families of the victims and our @nzpolice colleagues.'

While St John also took to twitter to write: 'Our thoughts are with colleagues from @StJohnNZ who have been responding to this incident and all of those affected at this very sad time.'

Channel Island politicians were quick to condemn the actions of those involved.

Jerseys minister for economic development Philip Ozourf was messaged by a relative in the country.

'Such shocking news from gentle NZ is hard to absorb - senseless loss of life at what appears to be at the hands of violent extremists, thoughts with the 49 known victims, their loved ones, the injured and all peace-loving New Zealanders.'

While Policy & Resources president Deputy Gavin St Pier said his thoughts lie with Christchurch today.

'The dead, injured, grieving and the community,' he said.

'It's sickening and incomprehensible that there are people who hate others they have never met simply because of their faith, skin tone, sexuality or goodness knows what else.'

Deputy Jonathan Le Tocq said he was standing with New Zealand after hearing the sickening news.

'Such hatred & violence never resolves anything for those who draw the sword will die by the sword,’ he said.

Deputy Dawn Tindall also commented on the events.

'My thoughts and prayers are with New Zealand - - people who perpetuate such violence should be utterly rejected and condemned,' she said.
