At least 35 people have been killed and more than 50 injured in a double suicide bombing north of the Iraqi capital, Baghdad, army sources say.
The two attackers mingled with a crowd of would-be recruits at an army base in the city of Baquba and then blew themselves up simultaneously, they say.
At least one of the bombers is said to have been disguised as a soldier.
Meanwhile, US forces in Iraq say they have detained 15 suspected insurgents, including an alleged al-Qaeda leader.
The bomb attacks at the al-Saad army camp in the east of Baquba took place at about 0800 (0500 GMT).
