Aamir Khalil said Pakistani officials last week ended the detention of bin Laden's relatives for living in Pakistan illegally, CNN reported.
"The family was kept safe and sound in a guest house," a Pakistan Interior Ministry spokesman said. "They have been deported to the country of their choice, Saudi Arabia, today."
The widows -- identified by U.S. and Pakistani officials as Amal Ahmed Abdul Fateh, Khairiah Sabar and Siham Sabar -- had been in Pakistani custody since the May 2011 U.S. Navy SEALs raid that killed bin Laden in his Abbottabad compound, where he hid for years under the nose of Pakistan's military.
Saudi authorities declined to comment on the deportation order, CNN said.
