The experts' report released today said the "scale of digital activity linked to ISIL and, to a lesser extent, some Al-Qaeda affiliates is of deep concern" and that the Security Council should take action. ISIL is another way to refer to the Islamic State group.
The report recommended that a council committee invite Internet and social media companies to give a briefing on their efforts to "respond to the exploitation of their services" by Al-Qaeda, the Islamic State and their allies.
Islamic State has released videos of beheadings and other atrocities to shock and spread fear while its widespread use of Twitter accounts helps reach potential recruits.
The experts' report said "the digital space is the realm in which the threat may be evolving" from the jihadists in the future.
The European police agency Europol this week announced plans to establish a new police unit tasked with scanning the Internet for IS propaganda.
