Facebook Inc. wants the social network to be a "hostile environment for terrorists," Reuters reported June 4, citing an emailed statement by the company's director of policy Simon Milner.

The statement came after British Prime Minister Theresa May urged internet companies to take a tougher stance on extremist ideology following the recent terrorist attack in London. Milner said the company uses technology and human review to "aggressively" remove terrorist content from the platform and to inform law enforcement when there is an emergency indicating an imminent threat.

Twitter Inc., meanwhile, has also stressed that it is taking action against militant propaganda on its platform. Nick Pickles, U.K. head of public policy at Twitter, said the company suspended nearly 400,000 accounts in the second half of 2016.
