Indian-origin 'Jihadi Sid' praises Hitler in video monologue

London: A video has emerged which shows Indian-origin Islamic State (ISIS) terrorist suspect Siddhartha Dhar praising Adolf Hitler.

Dhar, who has been dubbed "Jihadi Sid" by the British media, uploaded the monologue about his hatred of Jews and "Zionism" on YouTube in 2014.

Praising the Nazi leader, he is seen saying: "Other people were aware of this evil doctrine and they did things to stop it. Like Adolf Hitler."

Dhar also mentions 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," he adds.

The 32-year-old former bouncy castle salesman from Britain is believed to be the masked man who appeared in a brutal ISIS beheading video.

The Hindu-born convert to Islam now goes by the name of Abu Rumaysah.

His sister, Konika Dhar, had appeared before a House of Commons Home Affairs Committee hearing last week over the possibility of her brother being the masked man.

"I'm still holding to the firm belief that what I'm seeing is not him and I haven't had verification otherwise. It's sort of the realisation that 'is he really my brother that has done this and I can't accept that he would ever do that. I can't accept it," the London-based law student had said.

Dhar had been arrested in September 2014 as part of an investigation into alleged support of the banned extremist group Al Muhajiroun.

But he managed to escape from the UK while on bail and is now believed to be in ISIS-controlled territory in Syria. The latest video is believed to have been recorded months before his arrest.
