At least 16 militants killed in Egypt security operation

16 militants were killed and four arrested in a continuing crackdown in Sinai region by Egypt’s security forces. The security operation launched on Friday involves troops from the Egyptian air force, navy and army as well as the police and border guards.

President Abdel Fattah al-Sisi, who is seeking re-election in March, ordered the armed forces in November to defeat militants an attack on a mosque killed more than 300 people. That attack is the deadliest terrorist incident in Egypt’s history.

Sinai has been under a state of emergency since October 2014, when Islamist militants killed more than 30 soldiers in a single operation.

The insurgency poses the greatest challenge to the government in a country that is both the most populous in the Arab World and a main regional ally of the United States.
