After the death of old Jihadi John, Indian-origin UK man Siddhartha Dhar alias Abu Rumaysah, who appeared in the latest ISIS video, is doubted to be the new Jihadi John. About 10 years ago, Siddhartha accepted Islam after marrying with a Muslim girl. His mother, Sobita Dhar, last saw him 2 years ago, ahead of his visit to Syria. Siddhartha sister, Konika Dhar said that she will kill him if he comes to home. In the latest video, Dhar was one among the ISIS terrorists, who shot dead five men on the charges of spying for the UK.
