The White House on Monday condemned the "heinous" terrorist attack in the Turkish border town of Suruc Monday that left at least 28 people dead and wounded 100 others.

The apparent suicide attack occurred midday at the Amara Cultural Park in Suruc, where a group of people had gathered to assist in reconstruction efforts in Kobani, a city in Northern Syria.

"Our condolences go out to the families of the victims, many of whom had come to that community to assist in reconstruction efforts in Kobani," White House spokesman Josh Earnest said. "We express our solidarity with the Turkish government and the Turkish people and reaffirm our undeterred resolve to the fight against the shared threat of terrorism."

Asked whether President Obama is concerned about the spread of Islamic Sate-affiliated attacks in other countries, Earnest noted that the administration continues to "be mindful of the destabilizing impact" groups like the Islamic State have on the region.

He also acknowledged Islamic State attacks in other parts of the region, calling the violence an important reason for Middle Eastern countries to fight the group in the U.S.-led coalition.

"That's why it's important to continue to mobilize other countries in our coalition's efforts, and that's why the president is pleased to have the support of many other Middle East countries" in the coalition airstrikes, he said.

It was the second time in three days that the White House issued a statement condemning a bombing attributed to either the Islamic State or an affiliated group.

Late Friday, the Islamic State carried out a massive car bombing in a busy market in Iraq that killed 126 adults and children celebrating the end of the holy month of Ramadan.

It was the Islamic State's most deadly bombing attack on a civilian target in Iraq, and the White House Saturday issued a statement calling it "abhorrent" and "yet another painful example of atrocities that the terrorist group ISIL continues to perpetrate against the people of Iraq."

The White House refers to the Islamic State as ISIL, another name for the group.
