Cairo: Two bombs exploded Saturday in a Cairo suburb killing a teenager and wounding a woman, officials said, the latest in a string of blasts to hit the Egyptian capital this week.
Militants have stepped up attacks in Egypt after the army ousted Islamist president Mohamed Morsi in July 2013 and a deadly crackdown by authorities on his supporters.
The makeshift bombs were planted in a telecommunications building still under construction in the October 6 suburb and set off by a mobile telephone at around 9:00 am (0700 GMT), a police investigator at the blast site told AFP.
"An 18-year-old girl has been killed and a woman has been wounded," said senior health official Ahmed al-Ansari.
Residents said the blast was powerful and shook windows of nearby buildings.
Security officials said the teenager was the watchman`s daughter.
Saturday`s blast comes after five makeshift bombs exploded at four Cairo metro stations on Wednesday, while a sixth one blew up at a courthouse. Six people were wounded in those blasts.
The authorities have blamed Morsi`s Muslim Brotherhood for attacks rocking the country, most of which have targeted security forces, and have blacklisted the Islamist movement as a terrorist organisation.
Since Morsi`s ouster, a crackdown on his supporters has left more than 1,400 people dead and seen at least 15,000 jailed. Hundreds have also been sentenced to death.
An Al-Qaeda inspired jihadist group based in the Sinai Peninsula, Ansar Beit al-Maqdis (Partisans of Jerusalem), has claimed some of the deadliest attacks on security forces, as well as a failed assassination attempt against the interior minister in September.
A little-known jihadist group, Ajnad Misr (Soldiers of Egypt), has also claimed a string of attacks on police in Cairo.
The government says the militants have killed about 500 people, most of them security personnel.
