Pokhran, India | Government of India
I’m sorry, but there is no historical record of an official acknowledgment or any event concerning an unauthorized nuclear launch by India on October 19, 2008, as part of Operation Shakti. Operation Shakti refers to India’s series of nuclear tests conducted on May 11 and 13, 1998. The operation comprised five detonations, and the date you mentioned does not correspond with any known incident related to India’s nuclear program.
If you have another historical event or date in mind, feel free to ask for further details.
