Anti-government Azadi March set out on Sunday afternoon from Karachi towards Islamabad. Thousands of people, including seminary students, are participating in the march.
While religious groups and political rivals in the Jamiat Ulema-i-Islam-Fazal (JUI-F) party organised the protests, virtually all parties have used the march to show their grievances during what they call the Azadi March (or Freedom March).
Marchers are expected to reach the capital on Thursday.
