Bambang Waluyo, Indonesian Deputy Attorney General, has said government planned to execute 30 death-row convicts in 2017.
He disclosed this on Monday in Jakarta during a parliamentary hearing.
Waluyo said that this year, his office is preparing to execute 18 convicts, after July 6, the Eid el-Fitr Muslim holiday, which ends of the holy month of Ramadan.
Meanwhile, the Justice Ministry said not less than 121 people are currently on death row in Indonesia, including 35 foreigners, mostly convicted of drug-related crimes.
It explained that they include; Mary Jane Veloso from the Philippines, Lindsay Sandiford from Britain and Frenchman Serge Atlaoui.
The ministry recalled that in 2015 Indonesia executed 14 convicts, all but two of them foreigners, in a move that drew international condemnation.
Under Indonesian law, each convict would face a squad of 10 gunmen.
Indonesian President Joko Widodo, who took office in 2014, has taken a tough stance against drug trafficking, saying that the country is facing a drug emergency.
