Here some text from Amnesty:
six executed, NINE more AT RISK
The Indonesian authorities executed six people by firing squad on 18 January. Nine more people are at risk of execution.
Rani Andriani alias Melisa Aprilia (Indonesian), Daniel Enemuo (Nigerian), Ang Kiem Soei (Dutch), Tran Thi Bich Hanh (Vietnamese), Namaona Denis (Nigerian) and Marco Archer Cardoso Moreira (Brazilian) were executed by firing squad just after midnight on 18 January. All were convicted of and sentenced to death for drug-related offences. Five of them were executed on Nusakambangan Island while Tran Thi Bich Hanh was executed in Boyolali district, both in Central Java.
Amnesty International is concerned that more executions will follow. The Indonesian government announced in December 2014 that 20 people are scheduled to be executed in 2015. Nine men are at imminent risk of execution after their clemency applications were rejected by President Joko Widodo in December 2014 and January 2015. They are Syofial alias Iyen bin Azwar (Indonesian), Harun bin Ajis (Indonesian), Sargawi alias Ali bin Sanusi (Indonesian), Myuran Sukumaran (Australian), Andrew Chan (Australian), Martin Anderson alias Belo (Ghanaian), Zainal Abidin (Indonesian), Raheem Agbaje Salami (Nigerian) and Rodrigo Gularte (Brazilian). They were convicted for either premeditated murder or drug-related crimes. Another two people have also had their clemency applications rejected.
Death sentences in Indonesia are carried out by firing squad. The prisoner has the choice of standing or sitting and whether to have their eyes covered, by a blindfold or hood. Firing squads are made up of 12 people, three of whose rifles are loaded with live ammunition, while the other nine rifles are loaded with blanks. The squad fires from a distance of between five and 10 metres.
