Shocking video has emerged showing a group of young Muslim children in Philadelphia singing of ‘chopping off heads’ so as to ‘liberate Al-Aqsa Mosque’ while ‘defending Palestine with our bodies.’

The clip, which was first uploaded to Facebook by the Muslim American Society Islamic Center in Philadelphia last month, shows a group of children wearing Islamic headdress adorned with Palestinian symbols and colors.

A translation of the video was provided by the Middle East Media Research Institute.

The Muslim American Society issued a statement on Saturday vowing to investigate the ‘unintended mistake and an oversight’.

Video which was uploaded to social media last month shows a group of Muslim children in Philadelphia singing about 'martyrdom' and 'chopping off the heads' of those who fight the 'army of Allah'

The clip was posted by the Muslim American Society Islamic Center in Philadelphia

‘Those who accept humiliation - what is the point in their existence?’ a child narrator in the film says. ‘Those who reject oppression are the ones who assert their existence, and they eliminate the injustice from the land of the Arabs’

The organization also said that the ‘person in charge’ of this specific event has been ‘dismissed.’

‘Those who accept humiliation - what is the point in their existence?’ a child narrator in the film says.

‘Those who reject oppression are the ones who assert their existence, and they eliminate the injustice from the land of the Arabs.’

At this point, the other children join in and begin singing: ‘Rebels! Rebels! Rebels!

‘Glorious steeds call us and lead us onto paths leading to the Al-Aqsa Mosque.

‘The blood of martyrs protects us. Paradise needs real men!

‘The land of the Prophet Muhammad's Night Journey is calling us. Our Palestine must return to us.

‘Oh Saladdin, your men are among us – shame will be washed away!’

MAS, a nationwide organization with more than 50 chapters in the United States, issued a statement saying it would investigate the video

Another girl seen in the clip chants: 'Our martyrs sacrificed their lives without hesitation.

‘They attained Paradise, and the scent of musk emanates from their bodies.

‘They compete with one another to reach Paradise.

‘Will Jerusalem be their capital city, or will it be a hotbed for cowards?’

Another girl adds: ‘We will defend the land of divine guidance (Palestine) with our bodies, and we will sacrifice our souls without hesitation.

‘We will chop off their heads, and we will liberate the sorrowful and exalted Al-Aqsa Mosque.

‘We will lead the army of Allah fulfilling His promise, and we will subject them to eternal torture.’

The Muslim American Society released a statement saying that the songs were not ‘properly vetted.’

‘While we celebrate the coming together of different cultures and languages, not all songs were properly vetted,’ the group said.

‘This was an unintended mistake and an oversight in which the center and the students are remorseful. MAS will conduct an internal investigation to ensure this does not occur again.’

MAS is a nationwide organization that boasts more than 50 chapters throughout the country, according to its website.

‘As a faith-based organization dedicated to moving people to strive for God-consciousness and a just and virtuous society, we affirm our long-standing position on our shared values of humanity.

‘We stand resolutely in our condemnation of hate, bigotry, Islamophobia, xenophobia, racism, anti-Semitism and all the illnesses of hate that plague our society.’

MAS said that it owns the property which is leased by a school, which staged the event.

The group said that the school ‘will form a local commission to aid in sensitivity training and proper oversight for future programs,’ according to the Philadelphia Inquirer.

The term ‘martyr’ has been used by Islamists to describe those who carry out suicide bombings and other terrorist attacks against civilians.

The ‘attainment of Paradise’ is a term that references the supposed ‘reward’ that ‘martyrs’ - or ‘shahids’ - receive upon sacrificing themselves for Islam.

The children sang of 'liberating Al-Aqsa Mosque,' the third-holiest site in Islam, in Jerusalem's Old City (above). It was built on top of the Temple Mount, the holiest site in Judaism. The Western Wall, a remnant of the Jewish Second Temple, is seen in the foreground. The Dome of the Rock and Al-Aqsa Mosque are above it

Islamic extremists promise that anyone who becomes a ‘martyr’ for the cause is rewarded with 72 female virgins in heaven.

Palestinian suicide bombings against Israelis were a frequent occurrence during the 1990s and 2000s.

Organizations like Hamas and Islamic Jihad sent suicide bombers into the heart of Israeli cities, killing hundreds and maiming thousands.

The Al-Aqsa Mosque, which is considered the third holiest site in Islam, is located in Jerusalem’s Old City.

It was built centuries ago on top of the Temple Mount, which is the holiest site in Judaism.

The 'Night Journey' is a reference to the belief in Islam that the Prophet Muhammad ascended to heaven on a winged mule from the Al-Aqsa Mosque.

The political status of the mosque and adjacent holy sites in the Old City is one of the sensitive issues of the Israel-Palestine dispute.

Israel captured control of the Old City as well as the West Bank and Gaza Strip in the 1967 Six-Day War.

Palestinians insist that East Jerusalem should be the capital of a future independent state, while Israel has vowed to maintain sovereignty over the entire city.

Saladdin is revered in Islamic history for his role in leading the military defeat of the Crusaders in the Levant during the 12th century.

The Anti-Defamation League, a leading Jewish organization, released a statement calling the video ‘extremely disturbing.’

‘Children should not be indoctrinated to hate,’ the ADL said.

‘These young people should never have been asked to make speeches and dance and lip-sync to songs that glorify violence against Jews and the State of Israel.

‘The conflict between Israelis and Palestinians is deeply complex and painful on all sides, and the only chance for a peaceful future is to teach our children to pursue peace.’

Rockets and missiles from Gaza killed three civilians in Israel while Israeli strikes killed 12 Palestinians, most of them militants, in surging cross-border fighting on Sunday, according to Gazan officials and the Israeli military.

Israeli Prime Minister Benjamin Netanyahu said he ordered the military to continue 'massive strikes' against Gaza’s ruling Hamas group and Islamic Jihad, in the most serious border clashes since a spate of fighting in November.

Israel’s military said more than 600 rockets and other projectiles - over 150 of them intercepted by its Iron Dome anti-missile system - have been fired at southern Israeli cities and villages since Friday.

It said it attacked more than 260 targets belonging to Gaza militant groups.

Gaza officials said Israeli air strikes and artillery fire killed 20 people including eight civilians since Friday.

A rocket that hit a house in Ashkelon on Sunday killed a 58-year-old man, police said.

He was the first such Israeli civilian fatality since the seven-week-long Gaza war in 2014.
