This time – and again – the attacks have rocked France on one of its most sacred days, Bastille Day, the country’s national day.

France has extended its terrorism-related state of emergency for another three months following the Bastille Day truck attack in Nice in which at least 75 people were killed and many others injured. 

The driver of a truck containing guns and grenades fired at a crowd and drove for about 100 metres over people along the French resort city's Promenade des Anglais.

And once again Australians have been victims of terror. Just like the September 11, 2001 attacks in America, or the Bali attacks in 2002 and 2005, Australians were among the casualties of the attack in Nice.

Even our own Governor-General Sir Peter Cosgrove, who is in France for Bastille Day celebrations, was caught up in the mayhem. 

Sir Peter said on Facebook: "On a day where Australians marched alongside their French counterparts, this cruel attack has struck innocents celebrating their national day."

These attacks tear at the heart of not only the country under siege at the time, but the entire world.

As the world mourns yet another attack on innocent lives, on people going about their business, on people celebrating their national day of pride, what should be causing division is actually doing the opposite.

The latest attack on France is only bringing the world together. As one we are mourning those who have senselessly lost their lives. As one we grieve for more innocence lost. As one we are abhorred and disgusted by those responsible for the loss of life.

French President Francois Hollande said: "France has been hit on its national day, July 14, a symbol of freedom.

"It's all of France which is under the threat of Islamic terrorism, so in these circumstances we must show absolute vigilance and a determination without end."

Yes, another attack is making us more vigilant when it comes to our own safety while travelling overseas. But, no, it will not stop us living our lives.

It only brings us closer together and more resolute that these terror attacks will not define who we are or what we do.

We pray for France and we pray for the whole world.
