The numbers arrested in Europe on suspicion of jihadist activities nearly doubled over the last two years, Europe's policing agency said today, with an alarming rise among women and young adults. <br/><br/>Europol in its annual EU Terrorism Situation and Trend Report said today, some 718 suspects were arrested on offences relating to jihadist terror last year as opposed to 395 in 2014. But actual attacks dropped from 17 in 2014 to 13 last year, of which six were linked to the Islamic State group.<br/><br/>The 62-page report also pointed out that women and children, as well as young adults played an increasingly important operational role. <br/>
