Dr Jamie Shea has been working with NATO since 1980 in a wide range of areas including external relations, press and media, and policy planning, and currently serves as Deputy Assistant Secretary General for the Emerging Security Challenges Division.
This division was established in 2010 to deal with a growing range of non-traditional risks and challenges including terrorism, the proliferation of weapons of mass destruction, cyber defence and energy security.
As thousands of men, women and children flee the war-ravaged region, terrorists are being infiltrated into the mass exodus heading to Europe.
Dr Jamie Shea said Britain and other countries must be “on our guard” to combat the threat.
IS chiefs have seized on mass migration from the region as an “attractive” way to get hardened terrorists into the West under the cover of refugees.
He was speaking as Britain was being urged to take thousands of African migrants following the sinking of a refugee ship from Libya with the loss of almost 1,000 lives.
In a speech to the Counter-Terror Expo in London, Dr Shea also gave a chilling insight into the scale and enormous wealth of IS.
He likened IS to a Mafia-style organisation with a £4billion fortune which was recently raking in £1.3million-a-day from oil revenues alone.
Referring to the migration chaos, Dr Shea told security industry delegates: “You can see it in the Middle East crisis, in the influx of refugees from Syria, the tragic capsizing of boats and also the sheer volumes of numbers – 5,000 in the last three days already entering Italy.
“There is no sign whatsoever that this flow of people is going to stop.
“IS is using this to infiltrate further terrorist operatives into Europe.”
“This is going to be a very, very big question to deal with for the refugee agencies.
“But we will need to be on our guard.
“Migration is certainly one thing IS finds attractive.”
