Cairo: Egyptian authorities on Sunday barred Yemeni Nobel Peace Prize winner Tawakkul Karman from entering the country, apparently over her criticism of the military for ousting Islamist president Mohammad Mursi.

Karman, a pro-democracy activist, was denied entry into Egypt on orders from security agencies, according to the state Middle East News Agency.

Karman had arrived at Cairo airport aboard a flight from the Yemeni capital Sanaa and was deported on the same plane. The news agency did not give a specific reason why she had been banned from Egypt.

Karman, who was awarded the 2011 Nobel Peace Prize, has repeatedly lashed out at Egypt’s military and expressed solidarity with Mursi’s supporters who have been protesting since his overthrow on July 3.
