The country’s Foreign Ministry spokesman Michael Tene said the government was not informed of the time Royati Beth Sabotti Sarona was executed.

“The Indonesian government called the Saudi ambassador in Jakarta for an explanation,” the spokesman said. He said the government had learned Sarona had confessed to murdering her sponsor Khairiya bint Hamid Mejlid.

“Without prejudice to the legal system in force in Saudi Arabia, the Indonesian government observed that the execution was carried out without observing international practices relating to consular protection,” Foreign Ministry spokesman Tene told AFP.

Tene expressed his “deep sorrow” over the execution. Sarona was found guilty of killing 70-year-old Mejlid by striking her repeatedly on the head with a meat chopper and stabbing her in the neck. The crime took place one and a half years ago.
