Attacks 'planned for weeks'
The attacks on Paris were probably planned for several weeks.
Intelligence analyst Dr George Friedman told Leighton Smith the atrocities have been designed to be as horrific as possible.
He said the aim is to generate hatred against Muslims, and therefore strengthen the Jihadist position.
Islamic State has claimed reasonability for the attacks in Paris, with authorities now working to verify the claim.
Terror expert Greg Barton said the fact the attacks were carried out without any warning is unusual.
"..still surprising that Intelligence was unable to pick up a plan as audacious as this one."
NZ Government condemns attacks
Prime Minister John Key was in sombre mood after hearing the news of the Paris attacks.
Political editor Barry Soper is travelling with the prime minister as he heads to Vietnam.
He said John Key's first concern was with the safety of his daughter who lives in Paris, but his wife Bronagh had quickly confirmed daughter Stephie was safe.
Barry Soper said the prime minister was told of the attacks through the plane's communication system.
Mr Key said New Zealand stands with the country in the global fight against terror.
He said our Consulate is working with authorities in France, to determine if any New Zealanders have been caught up in the attacks.

It appears the police operation to free the hostages held in the Bataclan concert hall in Paris has been successful, but not before 118 patrons were killed.
Journalist Peter Allen said police are saying the hostage takers have been killed.
"They've moved in, clearly to stop lives being lost. They had to move in very, very quickly...Sadly, it's a scene of carnage and many civilian have died."
The Daily Telegraph's Henry Samuel said the gunman got inside the concert hall, and opened fire on the crowd.
"Clearly if the security forces have launched an assault this quickly, they fear a blood bath is going on...There's no point in hanging around."
A New Zealand lawyer was hiding in a doorway at the edge of one of the police cordons in Paris.
Sefton Revell is in the 11th arrondissement of the city, and he was in a bar only a few hundred metres from the restaurant attack.
He said there's a massive convoy of police vehicles going up Boulevard Voltaire towards the Bataclan theatre.
"There's army guys with helmets and automatic weapons, and they're all looking back up the street. So, it's police, it's gendarme and army."
While he didn't see the shooting itself, he said he was on the way home he passed the concert hall where people were being held hostage.
French President Francois Hollande has now closed his country's borders, and declared a state of emergency.
Visibly shaken, he told told the people of France the terror attacks are not over yet.
Newstalk ZB correspondent in Paris Catherine Field agrees the situation is still unfolding.
"There were grenades, there were automatic weapons used, there were explosions.
"There are police everywhere, there are security alerts everywhere, there are ambulances everywhere."
She said the city is in a state of shock.
"No one expected that so quickly after the January attack we would be back to this situation here in Paris, where literally people on the streets in Paris, away from those areas, are standing around in shock saying, is this really what is happening to this city again?"
US security officials believe the attacks in Paris are coordinated.
Although there's been no official claim of responsibility, ISIS has been celebrating the attacks on Twitter, and eyewitnesses say they heard gunmen chanting Allahu Akbar.
CNN's terrorism analyst Paul Cruickshank said although there's been no official confirmation, it looks like a co-ordinated attack.
"Especially because of the reports of potential suicide bombers being involved, of Allahu Akbar being chanted by some of the shooters, because of the kind of weapons being used...this appears to be a coordinated, ongoing attack...some kind of spectacular terrorist attack."
US President Barack Obama has condemned the series of deadly attacks as an "attack on all of humanity", and pledged to work with France to bring those responsible to justice.
"Whenever these kinds of attacks happen, we've always been able to count on the French people to stand with us," Obama said in a brief speech from the White House.
"They have been an extraordinary counter-terrorism partner. And we intend to be there with them in that same fashion."
And British Prime Minister David Cameron said he's shocked by the events in Paris.
He said his thoughts and prayers are with the French people.
