"I am very thankful to be invited for the charity event "Humanity United Against Terror". I was eagerly looking forward to my performance as it is for such a great cause. But I am deeply disheartened for not being able to make it to an event of such generosity due to a last moment medical emergency in my family. I'm surely going to make it up for my fans, who would be disappointed about this and I wish RHC all the best for initiating such a noble initiative. Good Luck!" Ram Charan said.
