The White House condemned a massive car bombing by the Islamic State of Iraq and Syria that exploded in a busy market in Iraq, killing at least 126 adults and children who were there celebrating the end of the holy month of Ramadan.

National Security Council spokesman Ned Price said the "abhorrent" attack "which purposefully and viciously" targeted Iraqi civilians" celebrating the Eid holiday in Diyala province Friday night is the "yet another painful example of atrocities that the terrorist group ISIL continues to perpetrate against the people of Iraq."

The United States, he said, remains "steadfast in its commitment to work with Iraqi Prime Minister [Haider] al-Abadi and our partners in Iraq to bring an end to ISIL's depravity."

Iraqi and U.S. officials say the bombing injured more than a hundred more, making it the Islamic State's worst single bombing attack on a civilian target in the country.

The Islamic State claimed responsibility for the attack on Twitter and said the car held at least three tons of explosives.

Al-Abadi described the attack as a "heinous crime" that would not go unpunished, according to the Washington Post.
