The spate of attacks began in Paris on October 16th
when teacher Samuel Patty was beheaded by Chechnya teenager Abdullah Anzarov.
Less than two weeks later,a Tunisian man fatally stabbed three people in a church
in the French city of Nice.
He had arrived from Tunisia as a migrant via Italy.
And on November 2nd,
Islamic state sympathizer Kuchitim Fedjulai shot and killed four people in Vienna.
The leaders of those countries
along with other European heads of state and officials met Tuesday to discuss their response.
France and Germany called for much tighter security
on the border of Europes passport free travel area known as the Schengen Area.
Its not about reducing or cutting down the right to asylum.
But its clearly about implementing it fully
and fighting the pathways to misappropriated
and to better protect our common exterior borders.
The terrorists in both nice and vienna had moved freely between Schengen countries.
Securing the external border wont necessarily solve the problem,
says terror analyst Rafael Pantucci.
As weve seen repeatedly in the past,you know terror attacks tend to come from within.
And I think the last incident we saw in Austria was another example of this in many ways.
Well the individual involved may be a second generation immigrant.
He was actually born in Austria.
So how should governments tackle the threat of homegrown radicalization?
Europe is proposing new laws to crack down on internet companies hosting extremist content.
The moment they are given evidence that
there is something on their sites that is criminal or damaging.
They have to react straight away and quickly.
The EU meeting took place on the fifth anniversary of the coordinated terror attacks in Paris,
when nine attackers killed 130 people.
Since then most attacks in Europe have been carried out by so-called lone wolf terrorists.
Its infinitely better place to be than seeing large-scale attacks
like we saw in Paris or Madrid or London earlier these decades.
The 27 European union heads of state are due to meet again in december
to decide concrete steps on tackling the terror threat.
