The White House says it is horrified by the brutal attack in Syria that killed more than 90 people, including at least 32 children.

National Security Council spokeswoman Erin Pelton said Saturday that the attack serves as a "vile testament to an illegitimate regime" of President Bashar Assad. The head of the U.N. observer team said the assault on Houla, a group of villages northwest of the besieged city of Homs, killed more than 60 adults and at least 32 children under the age of 10.

The White House said the Syrian regime responds to peaceful political protest with "unspeakable and inhuman brutality."
