Most of Western Europe is at "high risk" from terrorist attack, according to broking giant Aon.
The global terrorism risk map from Aon provides a new assessment of terror risks across the world.
It is the first time the broker, which employs former military specialists to help make its assessments, has compiled a map of terrorism risk, although it has previously done a similar exercise for political risks.
Central and South American countries are designated either "low" or "negligible" risk. Northern Ireland was seen as under a lesser threat of terrorist attack than the rest of the UK.
While the UK remains vulnerable to attack from the IRA, the assessment concludes the group appears to have no current intention of using it.
Aon's special risks division chairman Paul Dobbs said: "If you want to get mugged, go to Latin America - but as far as explosions are concerned, the risks are practically negligible, outside Colombia."
He warned: "Most terrorist organisations active in the 1970s and 1980s had clear political objectives. They tried to calibrate their attacks to produce just enough bloodshed to get attention for their cause, but not so much so as to alienate public support. Now, a growing percentage of terrorist attacks are designed to kill as many people as possible."
