Imran Khan's supporters protest outside hospital

STORY: The protesters chanted: "Long live Imran Khan" and "Imran, you have numerous comrades to sacrifice their lives."

Khan was shot in the shin on Thursday when his anti-government protest convoy came under attack in the east of the country, in what his aides said was a clear assassination attempt by his rivals.

Khan, ousted as prime minister in a parliamentary confidence vote in April, was six days into a protest procession bound for Islamabad, standing and waving to thousands of cheering supporters from the roof of a container truck, when the shots rang out.
