One killed and six wounded in string of bomb blasts in Cairo

Four small bombs explode in four Cairo metro stations early Wednesday, causing six injuries, while two others detonate near a Heliopolis courthouse damaging only vehicles. On Tuesday night, a tractor operator was also killed in a bombing in 6th of October City, according to the Ministry of Interior.
 Three small bombs exploded minutes apart in three Cairo metro stations during early morning rush hour on Wednesday, injuring at least five people, according to Al-Ahram's Arabic news website. A fourth blast in the afternoon injured a sixth passenger. The blasts injured three people at the Shubra station, while state TV reported one injury at the Ghamra station. A senior ambulance official, Mohamed Sultan, said the fifth injury occurred at the Hadyek Al-Quba station, and the sixth injury took place at the Ezbet Al-Nakhl station. It seems that one of the wounded at the Shubra station, was a person who carried the bomb.
The two improvised bombs in Heliopolis were placed underneath two cars outside a courthouse, Al-Ahram said, adding that the blasts damaged the cars but left no injuries. A third home-made explosive device planted in the vicinity was defused.
Islamist militants had stepped up attacks in Egypt since the army's ouster of Islamist president Mohamed Morsi last July. Most of the attacks, mainly targeting security forces, had been initially focused in the sparsely populated Sinai Peninsula but eventually spilled over into other cities, including Cairo and the Nile Delta.
