The White House has introduced new initiatives to combat recruitment of Americans to extremist groups like the so-called Islamic State.

Among a raft of measures is the creation of a new task force to counter the online propaganda of terror groups. The announcement comes as administration officials meet leaders from Silicon Valley to discuss ways that technology can thwart terrorists. Participants include Apple, Google, Facebook, Microsoft and Twitter. The aim is to prevent extremist groups radicalising others and encouraging violence online.

The White House initiatives include a new task force for countering violent extremism, established by the Department of Homeland Security and the Department of Justice.

The State Department also announced a new Global Engagement Center, which will focus on enabling foreign audiences to counter pro-IS messages.
