Amnesty International has condemned the execution of six Taiwanese prisoners as “cold-blooded killings”.
The six men had been convicted of murder and were executed in three prisons across the island.
"How can the government credibly claim it wants to see an end to the death penalty when it continues to conduct such actions," said Amnesty International in a statement.
"It is abhorrent to justify taking someone's life because prisons are overcrowded or the public's alleged support for the death penalty."
Taiwan has now executed a total of 15 prisoners since 2010, after an informal halt on the death sentence was established in 2005.
Public calls for executions have recently increased after a high-profile murder of a young boy in a video arcade.
