Washington: After days of criticism from staff past and present, social network Facebook says it is looking at improving content policies, while building products to advance racial justice.

Chief Executive Officer Mark Zuckerberg announced the moves on Friday in response to ongoing protests in the United States.

Zuckerberg's post comes after Facebook faced widespread backlash, including from its own employees, over its decision to leave up controversial posts from President Donald Trump.

"I know many of you think we should have labelled the President's posts in some way last week", Zuckerberg said in a blog post, referring to his decision to not remove an inflammatory post by Trump containing the phrase "when the looting starts, the shooting starts."
