BAGHDAD // Iraqi officials say a bombing targeting a stream where children had sought refuge from the summer heat has killed four people.
It was the second such attack in less than a week.
Police officials say the bombing took place on Wednesday in Wajihiya, a town 80 kilometres northeast of Baghdad. Two swimmers and two passers-by were killed.
Hospital officials confirmed the casualties. All officials spoke on condition of anonymity because they are not authorised to speak to the media.
Violence has been on the rise since the start of Ramadan. Earlier this week, a mortar attack on swimmers in the Tigris River killed four people.
