"Our latest reports said that eight policemen and three civilians were killed, along with 16 people wounded by the attack, " the source told Xinhua on condition of anonymity.

A suicide bomber blew up his explosive vest among a crowd of people lined up at the rear of the Police Academy building in eastern Baghdad to sign up to join the Iraqi police, the source said.
