SHOCKING video has emerged showing children as young as six spouting anti-Western rhetoric and waving Islamic extremist flags in Sydney, Foreign Minister Julie Bishop says.

A Muslim youth group in the city’s southwest has been accused of indoctrinating young children after video surfaced from a performance in Lakemba last year.

In the YouTube footage aired by the Seven Network, the four boys aged six to 13 wave flags, including the one used by Islamic State, and chant “You’re never too young to be a Soldier for Khilafa”. They call for US President Barack Obama to “go to Hell”, and say they want the head of Syrian President Bashar al-Assad.

Ms Bishop says children should be playing in their playgrounds with friends and “not being enlisted by irresponsible adults to an ideology that preaches hatred against the country in which they live”.

The Muslim Youth Project reportedly has links to Hizb ut-Tahrir, the radical group recently labelled “un-Islamic” and “un-Australian” by Prime Minister Tony Abbott.

NSW Family and Community Services Minister Gabrielle Upton has asked her department to investigate the youth group.
