Agony of the last goodbye on Bali Nine death row: Distraught families of two Australians facing the firing squad TONIGHT collapse in tears as they see their loved ones for the final time

Two Australian drug smugglers set to be executed by firing squad in Indonesia have entered their final hours - with their families collapsing in tears as they said their goodbyes. Andrew Chan and Myuran Sukumaran (inset) are expected to be executed at around midnight on the Indonesian island of Nusakambangan - 5pm UK time. The relatives were mobbed by journalists as they arrived at the prison (main and left, which shows Sukuraman's mother). The shooting is set to go ahead despite Indonesia's Constitutional Court agreeing to hear a legal challenge brought by the duo and setting a hearing date of May 12. Chan and Sukumaran are part of the Bali Nine who were convicted in 2005 over a plot to smuggle around 18.2lbs of heroin from Indonesia to Australia. The pair, as well as other death row inmates, have remained defiant in their final hours inside the prison on Indonesia's 'death island', where coffins were seen arriving earlier this evening (bottom right). Chan married his fiancé of less than three months while inside prison (top right).
