Twin explosions hit Cairo

Two explosions have gone off in the space of two minutes in the Egyptian capital, with residents saying the blasts were followed by ambulance sirens.

Egypt has seen a wave of attacks claimed by jihadist groups since the army last year removed its first freely elected president, Islamist Mohamed Morsi, and cracked down on his supporters.

   

"There was one powerful blast at 9:45 am (0745 GMT), followed by another, less powerful, two minutes later," a resident said.

   

The resident said the explosions sounded as though they came from an area near Cairo University of the sprawling Giza district, which is home to the Pyramids.

   

Another resident said ambulances and fire engines were converging on Giza.
