Shiromani Gurdwara Parbandhak Committee (SGPC) chief Harjinder Singh Dhami on Sunday asked the Sikh community to observe the martyrdom day of the sons of Guru Gobind Singh as 'Sahibzade Shahadat Diwas' instead of 'Veer Bal Diwas.' "Observing the martyrdom day of 'Sahibzadas' as Veer Bal Diwas by the government of India is a mischievous conspiracy to undermine the greatest martyrdom ... in the world's religious history," Dhami said.
