TEHRAN, Young Journalists Club (YJC) - They said police and emergency workers intercepted the bomber as he entered the park in Shoala, in northern Baghdad, but he managed to set off his bomb before being caught.
At least 16 people were wounded in the attack, which the officials said could have claimed many more victims if the bomber had gotten himself deeper into the park before blowing himself up.
The officials spoke on condition of anonymity because they were not authorized to speak to the media.
Baghdad's parks, outdoor eateries, cafes and commercial areas are usually packed during Ramadan starting shortly after sunset until the small hours of the next day when Muslims eat their last meal before they begin their daily dawn-to-sunset fast.
There was no immediate claim of responsibility for the bombing, which bore the hallmarks of Daesh terrorist group.
