Secretary of State Mike Pompeo said Sunday that several U.S. citizens were among those killed in a string of attacks on churches and hotels in Sri Lanka on the Easter holiday, blaming "radical terrorists" for the devastating blasts.

"The U.S. Embassy is working tirelessly to provide all possible assistance to the American citizens affected by the attacks and their families," Pompeo said.

More than 200 people were killed and 450 injured in a series of bomb blasts that hit churches and hotels in Sri Lanka on Easter Sunday. Some of the attacks were suicide bombs, authorities said.

"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.

Sri Lankan security forces arrested seven people in a raid on a house in the capital hours after the attacks. Three police officers died in the raid.

Nobody has claimed responsibility for the attacks.

British, Danish, Turkish, Dutch, Indian and Chinese nationals were also killed in the attacks.
