CAIRO, Jan 29 (Aswat Masriya) - "Terrorist" elements launched today's attacks against security installations in North Sinai as a result of the armed forces' recent "successful blows" against them, the army spokesman said Thursday night.

Army Spokesman Mohamed Samir's statement, published on his official Facebook page, comes following the attacks against military and police facilities in North Sinai, which left at least 25 dead and over 36 injured.

Samir added that the attacks were also due to "the failure of the terrorist Muslim Brotherhood and its supporters at spreading chaos on the fourth anniversary of the great January 2011 revolution."

The attack claimed the lives of both civilians and military personnel, Egypt's state television reported, citing a health ministry official.

According to state TV, ten mortars and a carbomb hit the North Sinai security directorate earlier.

An army battalion was also targeted in the carbomb attack.

Egypt's state newspaper al-Ahram's office was reportedly destroyed in the attack, Reuters reported, citing state TV and Ahram.

There was no immediate claim of responsibility of the attack.

President Abdel Fattah al-Sisi declared a state of emergency and a curfew in the border governorate last October, in reaction to a militant attack which left over 30 security personnel killed.

It was extended until April 25, the cabinet said in a statement earlier this week.

Militants have stepped up attacks targeting security forces in Egypt, particularly in the Sinai peninsula, since the ouster of Islamist President Mohamed Mursi in July 2013.
