MORE than 20 trainee suicide bombers and their teacher were killed in Iraq when the tutor mistakenly detonated the bomb.
Security forces were drawn to the area by the sound of the explosion. They arrested 22 survivors, some of whom were wounded, and discovered seven fully prepared car bombs along with suicide belts packed with high explosive.
The dead instructor was described as an experienced operative. An Iraqi army officer told 'The New York Times' that his final lesson had killed "the bad guys for once".
The Islamic State of Iraq and Syria (ISIS), an extremist group affiliated to al-Qa'ida, ran this particular camp located in a largely Sunni area of central Iraq. ISIS also operates over the border in neighbouring Syria and controls areas of Anbar province in western Iraq.
Bomb attacks carried out by ISIS and other extremist groups are claiming hundreds of lives in Iraq every month. The country is now enduring its bloodiest period since the sectarian civil war of 2006-2007.
The discovery of the training camp amounts to one of the few setbacks for ISIS's campaign in recent months.
