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.”
