At least 26 people, mostly soldiers, have been killed in a series of attacks by Islamist militants in the north of Egypt's Sinai Peninsula.
A car bomb and rockets hit a military base and a military hotel in the city of El-Arish.
Other attacks have also taken place in the town of Sheik Zuwayid and in Rafah, which is situated along Egypt's border with Gaza.
More than 50 people have been wounded in Thursday's attacks.
A militant group allied to the Islamic State is claiming responsibility.
Thursday's attacks represent some of the worst anti-government violence in Egypt in months.
The attacks come at the same time Egyptians took to the streets to mark the 4-year anniversary of Hosni Mubarak being unseated as President.
For more on the violence in Egypt, CRI's Poornima Weerasekara spoke to Ben Liang, a freelance Journalist and an expert on Egyptian affairs.
