Indonesia's president said on Tuesday the planned execution of 11 convicts on death row, most on drugs charges, would not be delayed. He warned foreign countries not to intervene in Jakarta's right to use capital punishment.

President Joko Widodo has denied clemency to the convicts despite repeated pleas from Australia, Brazil and France, who have citizens due to be executed soon by firing squad.

"The first thing I need to say firmly is that there shouldn't be any intervention towards the death penalty because it is our sovereign right to exercise our law," President Joko Widodo told reporters.
