The Pakistani government is preparing for a protest by supporters of jailed former prime minister Imran Khan, It's sealed off the capital with shipping containers and shut down major roads leading into Islamabad. Some mobile and internet services have been suspended. The march to the capital comes days ahead of a special court hearing, where Khan is expected to be indicted on terrorism charges. He's been in prison for more than a year and is facing more than 150 criminal cases. Khan and his supporters say the charges are politically motivated.
