Greece has achieved the distinction of being the country whose ranking has declined the most over the last year:
The largest fall in rankings belongs to Greece, which dropped from 57 to 24 to overtake Spain (27) and become the European country most at risk from terrorist attacks. Between June 2009 and June 2010, the country experienced 180 attacks – more than took place in Yemen. Recently, small left-wing groups have re-emerged, attacking a range of targets. Attacks tend to be non-fatal, but they can be highly disruptive as was seen in early November 2010, when a series of parcel bombs were addressed to embassies in Athens as well as European leaders and institutions.
Maplecroft characterizes Greece’s terrorism risk as being due to multiple attacks by “small left-wing groups” over the last year.
