Setting off to kill Australia's Bali Nine drug duo: Heavily armed firing squad in full body armour head to Indonesian prison island where two men are due to be shot tonight

Two Australian drug smugglers set to be executed by firing squad in Indonesia have entered their final hours - with the heavily armed police who will shoot them dead pictured heading to their prison by boat in full body armour (main). Andrew Chan and Myuran Sukumaran (bottom right) are expected to be executed at around midnight on the Indonesian island of Nusakambangan - 5pm GMT - and were visited by their emotional families in prison today (top right). Sukumaran's mother, Raji, made a hugely emotional appeal for her son's life to be spared.
