The US Government has met with several technology companies to discuss ways to combat terrorism and counter violent extremism online.
Senior officials from the White House and across the President Barack Obama’s national security team met with executives from Apple, Facebook and several other technology firms.
Yahoo, LinkedIn, YouTube, and PayPal and DropBox were also present at the meeting.
A Facebook spokesperson said: "This meeting confirmed that we are united in our goal to keep terrorists and terror-promoting material off the Internet.
"Facebook does not tolerate terrorists or terror propaganda and we work aggressively to remove it as soon as we become aware of it."
The US Government has also established a taskforce to counter online propaganda by the Islamic State and other militant groups.
A new group, dubbed Countering Violent Extremism Task Force, will integrate and harmonise government efforts to prevent violent extremism in the US.
The State Department will also set up the global engagement center, which will allow the US to increase focus on empowering and allowing the voices of international partners, governmental and non-governmental, and shift away from direct messaging.
