(CBS NEWS) – A series of eight bombings in Sri Lanka targeting Christian churches and hotels in three cities killed at least 207 people and wounded up to 450 others on Easter Sunday. Defense Minister Ruwan Wijewardene described the coordinated blasts as a terrorist attack by religious extremists.

The secretary of state condemned the attack in a statement Sunday morning and said “several U.S. citizens were among those killed.”

“Attacks on innocent people gathering in a place of worship or enjoying a holiday meal are affronts to the universal values and freedoms that we hold dear, and demonstrate yet again the brutal nature of radical terrorists whose sole aim is to threaten peace and security,” Pompeo said. “The U.S. Embassy is working tirelessly to provide all possible assistance to the American citizens affected by the attacks and their families.”
