France, Turkey and Tunisia are among places cited as hotspots
Some 80% of Irish holiday-makers say they will avoid travelling to places they perceive to be at risk from terrorist attacks.
A new survey shows 94% cited France as the country most at risk from terrorism, with Turkey and Tunisia also ranked highly - at 91% and 87% respectively.
Mexico (72%), South Africa (68%) and Russia (46%) were perceived to be the most risky in relation to crime, according to the research from 123.ie.
The survey was carried out among 771 adults in Ireland and covered a range of issues - including popular foreign and Irish destinations and risk.
Spain is the most popular destination for Irish holiday-makers at 41%, with more than one million of us flocking there every year.
While 36% of people say they will head to the UK.
Some 14% of those taking a foreign holiday have selected a trans-Atlantic trip to the US, and 15% have chosen Portugal for their break.
But it also shows that 17% of people are opting for a staycation with Galway city (31%) and Killarney (29%) chosen as the favourite home destinations.
Dingle was selected as a favourite Irish holiday spot by 24%, followed by west Cork at 23%.
And the research also showed that popular holiday types also included a world cruise (38%), which appealed to all age groups, with the same percentage selecting a US road tip.
Disneyland was chosen by 24% and 11% would enjoy going backpacking.
When asked about the issue of health, India was cited by 61% as the country that poses the greatest health risk - followed closely by Brazil.
Russia and Greece's political regime and instability were cited as a risk to travel by 44% and 42% of respondents respectively.
"People's views are obviously influenced by recent attacks in Turkey and last year's attacks in Paris and Sousse and this has been reflected in their responses, which is totally understandable," said Padraig O'Neill, head of marketing at 123.ie.
"Thankfully, the research also indicates that this hasn't stopped people from travelling abroad and almost three-quarters are planning a foreign holiday this year," he added.
