Police clash with Imran Khan supporters in Islamabad as tensions rise over rally for his release

Pakistani police have arrested over 4,000 supporters of former Prime Minister Imran Khan, including five lawmakers, ahead of a rally demanding his release from prison. Islamabad is under lockdown, with roads blocked and mobile data suspended in some areas. Clashes between Khan's party, Pakistan Tehreek-e-Insaf (PTI), and police have been reported, with injuries on both sides. The government claims the security measures are for public safety, while PTI argues they are politically motivated. Despite restrictions, PTI supporters remain active on social media. The U.S. Embassy has issued a security alert for Americans in Islamabad, advising caution around large gatherings, which may become violent.
