The two convicted Australian drug smugglers were being transferred on Wednesday from a Bali prison to an island for execution along with other foreigners, underlining Indonesia's determination to use the death penalty despite international criticism. The planned executions of Myuran Sukumaran, 33, and Andrew Chan, 31, have ratcheted up diplomatic tensions between Australia and Indonesia following repeated pleas of mercy for the pair, who are among 11 death row convicts scheduled to go before a firing squad.
