Pakistan's former military ruler Pervez Musharraf left the country early Friday, a day after the Supreme Court lifted a ban on him travelling abroad, airport sources confirmed to AFP.

Musharraf boarded an Emirates flight bound for Dubai that departed from Karachi airport at 3.55 am (2355 GMT). "He was the last person to be embarked on the plane and then the gate was closed," an airport source told AFP.

Lawyers for the retired general and former president, who is facing multiple charges including treason, have said he needs urgent spinal treatment not available in Pakistan.
