Video has emerged from an Islamic center in Philadelphia showing children singing songs and reading poems saying they would sacrifice themselves and kill for Allah.

According to Middle East Media Research Institute (MEMRI), the video was uploaded on April 22nd to the Facebook page of the Muslim American Society Islamic Center in Philadelphia.

In the video, children are seeing singing: “Glorious steeds call us and lead us [to] the Al-Aqsa Mosque. The blood of martyrs protects us… Take us, oh ships… until we reach our shores and crush the treacherous ones… Flow, oh rivers of martyrs!”

A young girl reads: “We will defend [Palestine] with our bodies… We will chop off their heads, and we will liberate the sorrowful and exalted Al-Aqsa Mosque… We will subject them to eternal torture.”

The Muslim American Society (MAS) operates 42 chapters in the United States. According to its website, the MAS’ mission is to “move people to strive for God-consciousness, liberty and justice, and to convey Islam with utmost clarity,” and that its vision is “a virtuous and just American society.”

The MAS released a statement on the video, via Facebook late Friday:
