Pakistani police fired tear gas to disperse followers of former Prime Minister Imran Khan in Karachi on Sunday, just days before a crucial national parliamentary election. Khan, barred from contesting due to a criminal conviction, faced a gathering of his supporters. An Associated Press journalist witnessed the arrest of approximately 20 to 30 individuals during the rally. Police reported the detention of twelve members of Khan's political party for assaulting officers and obstructing the thoroughfare.
