G7 countries and tech giants including Google, Facebook and Twitter on Friday (October 20th) agreed to work together to block the dissemination of extremist ideology over the internet, AFP reported.
Italian Interior Minister Marco Minniti said the internet had provided fertile ground for extremist "recruitment, training and radicalisation".
Officials said the accord aimed at removing extremist content from the web within two hours of being posted.
Britain's Home Secretary Amber Rudd insisted "companies need to go further and faster to not only take down extremist content but also stop it being uploaded in the first place".
The meeting on the Italian island of Ischia off Naples also focused on ways to tackle the threat of extremist fighters fleeing Syria, as the EU promised to help close a migration route considered a potential back door for terrorists.
Minniti said the G7 ministers had discussed how to go about "de-radicalising" citizens returning from the ISIS frontline, to prevent them becoming security risks in jails.
The ministers had brainstormed how to tackle the legal headache of prosecuting returnees.
The US and Italy signed an agreement on the sidelines of the G7 meeting to share their fingerprint databases in a bid to root out potential extremists posing as asylum seekers.
