The US has decided not to endorse a global pledge to step up efforts to prevent internet platforms from being used to spread extremist ideals, despite it being endorsed by a host of other nations.

The US cited respect for freedom of expression and freedom of the press for not following through on the agreement made at a meeting of world leaders and tech giants in the wake of the Christchurch attack.

Under the agreement, signatories would “encourage media outlets to apply ethical standards when depicting terrorist events online, to avoid amplifying terrorist and violent extremist content.”
