CAIRO, (Reuters) -
A small homemade bomb exploded near St Mary's Church in Zeitoon, in the Egyptian capital on Sunday but no one was hurt, security sources said.
The device damaged a car and a second one was found and detonated by police in the same area near a Coptic church in the northeast of Cairo, the sources added.
The official news agency MENA reported that a car burst into flames because of an electrical short circuit near the church and said the fire was swiftly extinguished. It did not mention a second blast.
Shady Wagih, a witness at the scene, told Reuters the first blast occurred at about 9 p.m. (1800 GMT), damaging the car and prompting police to set up a security cordon. The second blast occurred later after the police cleared the area, he said.
In February, a bomb exploded in a popular tourist area in Cairo, killing a French teenager. That was the first deadly attack on tourists in Egypt since 2006.
Egypt, with a population of about 80 million, is predominantly Muslim but has a large Christian minority, most of them Copts. (Writing by Edmund Blair; Editing by Charles Dick)
