The four were Freddy Budiman of Indonesia, Seck Osmani of Senegal, Humprey Eijeke and Michael Titus of Nigeria.
"The body of Freddy will be taken to Surabaya, the body of Humprey will be cremated in Banyumas, while the bodies of the two Nigerians will be flown to their country of origin," Junior Attorney General for General Crimes Noor Rachmad said on Friday.
The executions of the other death row inmates would be made public later on, he said.
"Right now we do not know whether the remaining death row inmates have appealed for clemency. Based on the result of our study with the existing team, only four would be executed for the time being. There are a lot of things we must take into account," he said.
Attorney General H.M. Prasetyo said earlier 14 drug convicts on death row would face the firing squad.
The 14 death row inmates are Freddy Budiman, Merri Utami, Pujo Lestari, and Agus Hadi of Indonesia, Zulfiqar Ali of Pakistan, Gurdip Singh of India, Onkonkwo Nonso Kingsley, Obina Nwajagu, Michael Titus Igweh, Humprey Ejike Nih, Eugene Ape, and Gajetan Acena Seck Osmane of Nigeria, and Ozias Sibanda and Frederik Luttar of Zimbabwe.(*)
