The terror attack in Nice, France on Thursday has underlined the continued problems facing governments and officials despite a major increase in security and intelligence sharing following the atrocities in Paris last year.
French President Francois Hollande said the attack Thursday was undeniably of a terrorist nature. He extended the current state of emergency in the country for another three months which will see more police on the streets. But, security analysts have told CNBC that attacks of this nature are largely unpreventable.
"It's quite impossible to prevent this kind of thing. It could happen anywhere, in any country at any moment," Claude Moniquet, a former intelligence agent at the French Directorate-General for External Security, told CNBC Friday.
