continuation of a downward trend that
started in 2014 when there were 226
attacks, followed by 211 in 2015.
The largest number of attacks in which
the terrorist affiliation could be identified
were carried out by ethno-nationalist and
separatist extremists (99). Attacks carried
out by left-wing violent extremists have
been on the rise since 2014; they reached
a total of 27 in 2016, of which most (16)
were reported by Italy. The number of
jihadist terrorist attacks decreased from
17 in 2015 to 13 in 2016, of which 6 were
linked to the so-called Islamic State (IS).
However, a precise ranking amongst and
within terrorist affiliations across the EU
cannot be established because the UK
does not provide disaggregated data on
attacks."
