Police arrest over 4000 Imran Khan supporters as Islamabad locks down ahead of rally

Pakistani police have arrested over 4,000 supporters of former Prime Minister Imran Khan ahead of a planned rally in Islamabad. The government has locked down the capital, using shipping containers to block roads and suspending internet services in certain areas. Khan, who has been in prison for over a year, faces more than 150 criminal cases, which his party claims are politically motivated. The police reported clashes with PTI supporters along highways connecting to Khan's strongholds in Punjab and Khyber Pakhtunkhwa. The government has restricted mobile and internet services in areas deemed security risks. Authorities have sealed off the Red Zone in Islamabad, warning that anyone attempting to enter will be arrested.
