At least 12 people killed on Saturday when two suicide bombers attacked a crowded swimming pool in Tuz Khurmatu, northern Iraq, a local official and police sources said.
45 others were wounded in the attack, also most of the victims were Shiites from the country's ethnic Turkmen minority.
Ali al-Huasaini, mayor of Tuz Khurmatu, said the attacker detonated his explosives vest at a swimming pool filled with families swimming in scorching summer heat.
"Innocent people were only trying to avoid the high summer temperatures, but they couldn't avoid death at hands of the worst criminals on earth," said Hussaini.

Another bomber then blew up explosives packed onto a motorcycle at the swimming pool's entrance as police and rescue teams were evacuating casualties, they said.
Hospital sources argue the death toll could rise, because many of the wounded were in critical condition.
No specific group claimed responsibility for the attack, however the ISIS has stepped up its attacks across Iraq, and carried out a horrid streak of suicide bombings including a huge attack earlier this month in Diyala province that killed more than 120 people.
Iraqi Security forces and Shiite militia groups (popular mobilization forces) are currently focused on recapturing swaths of the western province of Anbar, where they have recently lost Ramadi to ISIS’s grip.
The loss of Ramadi has been a huge setback in the battle against the militant insurgency, the Shiite militias and the Iraqi forces have been gearing up for weeks preparing for a grande offensive to retake the mainly Sunni governorate of Anbar and Iraq's largest province.
