A car bomb exploded near an army intelligence building in Egypt's Ismailia killing at least four soldiers Saturday, according to AFP. Part of the intelligence building also collapsed from the detonation.
Security personnel discovered another undetonated car bomb while sweeping the area following the attack.
Saturday's attacks were preceded by more violence in Sinai Friday that left a policemen dead. The North Sinai has particularly witnessed increased attacks since the oust of former President Morsi in July, with the Egyptian army most recently conducting a large-scale military operation to "clear the area" of armed militants the area in September.
