Local travel agents have reportedly fielded a number of calls from Europe-bound customers desperate to either change or cancel their itineraries.

It comes after a demented suicide bomber detonated an explosive in the foyer of Ariana Grande’s show at the Manchester Arena, killing 22 people and injuring at least 60 others. 

The massacre was the sixth act of terror in Europe in less than three years, deterring would-be tourists from making the trip. 

After booking a 12-day holiday spanning Greece, Paris and London three months ago, ​Wagga’s Terry Cranson decided to suspend his retreat. 

“I couldn’t even get myself pumped up for it anymore,” he said.

“There’s only so many disasters you can hear about before it completely changes your perception of the trip – and to me it wouldn’t feel like a holiday at all.

“We’re living in sad times.”

Mr Cranson was slugged with a series of cancellation fees, but it is a decision he does not regret. 

“It just doesn’t feel like the right time to be going anymore,” he said.

“All these major terrorist attacks seem to be happening in Europe.”

The attack was the deadliest to hit the country since the London bombings in July 2005.

Some of London's tourist attractions were shut down on Wednesday after the United Kingdom warned that another terrorist attack could be imminent.

A Wagga travel agent noted a reduction in Europe bookings since the harrowing Nice attack back in July 2016. 

“It certainly doesn’t help having another horrific disaster when people are already apprehensive,” she said.

“It’s still hugely popular with travellers, but there has been a reduction.

“I can understand why people would seek to change their itinerary.”

Prime Minister Malcolm Turnbull branded the attack “especially vile” due to the demographic targeted. 

“Surely there is no crime more reprehensible than the murder of children,” he told Fairfax Media. 

“This is a direct and brutal attack on young people everywhere, on freedom everywhere.”
