Senior White House officials and U.S. intelligence and law enforcement officials will meet with Silicon Valley executives on Friday to discuss the use of social media by militant groups, sources familiar with the meeting said on Thursday.
In an escalation of pressure on technology firms to do more to combat online propaganda from groups such as Islamic State, the meeting follows attacks in Paris and San Bernardino, California, that underscored the role played by social media companies such as Twitter Inc, Alphabet Inc's YouTube and Facebook Inc.
A source familiar with the meeting said it would focus on social media content, not encrypted communications, another topic of discussion between Silicon Valley and the White House.
Twitter, Apple Inc, Facebook and Google are attending, the companies said.
