The shooting dead of a prominent Pakistani investigative journalist by police in Kenya caused outrage in his home country, leaving many wondering how such a thing could have happened.

Thousands turned up to Arshad Sharif’s funeral on Thursday in Islamabad to mourn the well-known critic of Pakistan’s military.

Opponents of the current Pakistani government believe that he was targeted in a plot organised in Pakistan.

But Kenya’s police, in an initial report, said the 49-year-old was shot dead in a moving vehicle in a case of mistaken identity.

Pakistan says it has sent investigators to Kenya to help with the inquiry into what took place.
