London: A video has emerged showing Indian-origin Islamic State (ISIS) terrorist suspect Siddhartha Dhar praising Adolf Hitler.
Dhar, who has been dubbed 'new Jihadi John' by media, uploaded the monologue about his hatred of Jews and Zionism on YouTube in 2014.
Praising the Nazi leader, Dhar is seen saying, "Other people were aware of this evil doctrine and they did things to stop it. Like Adolf Hitler."
Dhar also mentioned the 'Protocols of the Elders of Zion', a discredited 1909 text claiming a Jewish plan for global domination, saying the document 'exposes their (Jews) hatred of humanity'.
"They have no qualms with wanting to subjugate them (other religions), oppress them and exploit them," Dhar said as he criticised companies owned by Jewish people, such as Warner Bros and Disney.
Dhar also praised the 'Khalifah' in Syria and Iraq and claimed 'it will convert everyone in the world to Islam'.
The 32-year-old former salesman from Britain is believed to be the masked man who appeared in a brutal ISIS beheading video.
The Hindu-born convert now goes by the name of Abu Rumaysah. His sister, Konika Dhar, appeared before a House of Commons home affairs committee hearing last week over the possibility of her brother being the masked man.
More than 700 Britons have fled to the Middle East to join the jihadi hate group since it was formed in 2011, with around half having since returned to our shores.
