Cairo police base rocked by deadly explosion

At least five people have been killed in three bomb blasts in Cairo apparently targeting police. The first blast at the police HQ, at about 6:15am local time, killed four and injured about 70 others, according to state sources. The blast, reportedly a bomb in a vechicle, also damaged the nearby Museum of Islamic Art building. In a second blast hours later, a small IED was detonated next to police vehicles near the Behooth metro station in the Dokki district. One person was reported killed in the explosion. A third blast hit a police directorate in Talbiya, in Giza. The explosion was caused by a crude home-made device, police said, and there were no casualties. The explosions came one day before the third anniversary of the revolution that brought down Hosni Mubarak, Egypt's third and longest-serving president. Al Jazeera's Mike Hanna reports from Doha.
