PHILADELPHIA (CBS) — The Muslim American Society is investigating a video that shows children reciting a violent poem in Arabic. The incident happened at a Philadelphia Islamic Center in April.

According to a translation, the children said, “We will defend Palestine with our bodies. We will chop off their heads.”

CBS3 has not independently verified that translation.

The Muslim American Society said in a statement it “rejects what happened” and called this an “unintended mistake and an oversight in which the center and students are remorseful.”

Philadelphia’s Anti-Defamation League also issued a statement, saying, “If the translation is accurate, it is extremely disturbing. Children should not be indoctrinated to hate.”
