BBC News reports: Militants have stepped up their campaign against security forces in Egypt with a series of explosions in the Egyptian capital, Cairo.

Six people were killed and some 100 others wounded, with the biggest blast outside Cairo’s police headquarters.

The attacks come on the eve of the third anniversary of the 2011 uprising against President Hosni Mubarak.

Meanwhile, seven were reported killed in clashes between security forces and Muslim Brotherhood supporters.

The explosion outside Cairo’s police headquarters left four people dead and wounded at least 76.
