Lahore: Pakistani social media star Qandeel Baloch has been allegedly strangled by her brother in what appears to be an "honour killing", shocking the nation.

Baloch's raunchy social media photos challenged social norms in Pakistan, a deeply conservative Muslim country.

Baloch received multiple death threats and suffered frequent misogynist abuse, but continued posting provocative pictures and videos.

In Facebook posts, she spoke of trying to change "the typical orthodox mindset" of people in Pakistan.
