At least four people were killed and 12 injured Friday in three separate attacks in Egypt, a media report said.
Two blasts took place in South Sinai's El-Tur city. In one blast, a suicide bomber wearing an explosives-laden belt blew himself up at a security roadblock, leaving two people dead and five injured, Xinhua reported.
The second blast took place 30 km farther from El-Tur, in the direction of Sharm El-Sheikh city, killing one and injuring four others.
The second explosion targeted a bus and those injured were tourist workers.
The third blast hit a traffic kiosk outside Heliopolis court complex in eastern Cairo, killing a police officer and injuring three officials.
Since the ouster of Islamist president Mohamed Morsi by the army last July, a wave of explosions has hit security personnel and their premises in the restive Sinai peninsula. Lately, the blasts have occurred in the capital and the Nile Delta cities.
