28 people have been killed and wounded 57 in a suicide bombing as recruits gathered at a police academy in central Baghdad.
Many police and police recruits were killed in the attack at the back entrance of the main police academy in the Iraqi capital.
The suicide bomber was wearing an explosive vest, and was riding a motorbike also packed with explosives, police said.
Police recruits have been a major target for militant attacks in the past.
On 1 December last year, an attack killed 15 police officers and recruits and wounded 45 other people outside the same Baghdad police academy.
