CAIRO — Officials say that Yemen's Nobel Peace Prize winner Tawakkul Karman has been denied entry into Egypt after she landed at Cairo airport.

Karman, the first Arab woman to win the Nobel Peace prize, has stated her opposition to the military coup that ousted fellow Islamist Mohammed Morsi on July 3 after days of mass protests in which millions of Egyptians demanded that he step down.

She said she had intended to join the larger of two sit-in protests by Morsi supporters in the Egyptian capital.

The Cairo airport officials said Tawakkul was sent back on the Sunday flight that brought her to Cairo from the United Arab Emirates.

The officials spoke on condition of anonymity because they were not authorized to speak to the media.
