A bomb went off near a public transport bus in the Egyptian capital on Thursday, injuring five people

A bomb went off near a public transport bus in the Egyptian capital on Thursday, injuring five people, security officials and a medic said.
  
Security officials said the improvised bomb had been placed next to a bus in the north Cairo neighborhood of Nasr City and police defused another bomb nearby. The victims received mild to moderate injuries, a health ministry official said.
  
The interior ministry said the bomb had been planted in a grassy area at the intersection of two busy streets in Nasr City. Militants have killed scores of policemen and soldiers in attacks since the military's overthrow of president Mohammad Mursi in July.
  
The bombing comes two days after a suicide car bomber killed 15 people, mostly policemen, in an attack on their headquarters in a Nile Delta city.
  
On Wednesday, the military-installed government declared Mursi's Muslim Brotherhood movement a terrorist group, and blamed it for the police headquarters bombing although a Qaeda-inspired group in the Sinai peninsula said it was responsible.
  
The Brotherhood, which organizes near daily protests demanding Mursi's reinstatement, insists it is peaceful and has condemned militant attacks.
