Hundreds of thousands of black-clad mourners lined the streets of Bangkok on Thursday to watch the elaborate procession to move late Thai King Bhumibol Adulyadej's royal urn from the Grand Palace to the Royal Crematorium, which officials built from scratch to create 'heaven' on earth. King Bhumibol -- also known as King Rama IX -- passed away last year at the age of 88 after ruling Thailand for seven decades.
