Caning as a form of judicial punishment in Malaysia has reached "epidemic" proportions and should be banned, according to a human rights group.
Blows administered to the body with a long cane are a legal punishment for more than 60 offences in the country.
Amnesty International claims at least 10,000 prisoners and 6,000 refugees are caned there each year.
The government says caning is a legal and effective deterrent from criminal activity.
Malaysia's law minister would not comment on the report but told the BBC that there are no plans to review the law.
Amnesty says the practice amounts to cruel and inhumane treatment as it leaves both physical and psychological damage, and should be banned.
"Across Malaysia, government officials regularly tear into the flesh of prisoners with rattan canes travelling up to 160km/h. The cane shreds the victim's naked skin, turns the fatty tissue into pulp, and leaves permanent scars that extend all the way to muscle fibres," Amnesty says in a report on the practice.
