Egypt's official MENA news agency says a top militant who was convicted and sentenced to death for the killing of 25 policemen in 2013 has been executed.

The report says Adel Habara's execution on Thursday came five days after his final appeal was rejected by the Cassation Court.

Habara was convicted for his role in the killing of the policemen in northern Sinai in August 2013, two months after the military overthrew the Islamist Mohammed Morsi, Egypt's first freely elected president.

Egypt has for years battled militants in Sinai, but attacks targeting security forces there increased after Morsi's ouster. The violence is blamed on a local affiliate of the Islamic State group, which has claimed responsibility for a suicide bombing that killed 25 people in a Cairo church on Sunday.
