By Uditha JayasingheCOLOMBO (Reuters) - Sri Lanka vowed to continue an anti-narcotics campaign that has seen more than 35,000 people detained over the last few weeks despite concerns raised by multiple rights groups, top officials said on Thursday. Sri Lankan police have detained 38,525 people since the operation - code-named "Yuktiya" or "Justice" - began in December. Thirty-three rights organisations including Amnesty International, Human Rights Watch, and International Commission of Jurists, this week expressed concerns over what they call "drastic intensification" of anti-narcotics operations in Sri Lanka leading to significant human rights violations. There is no reasonable suspicion, the kind of people arrested have a lower marginalised economic status," said Thiyagi Ruwanpathirana, a researcher for Amnesty International Sri Lanka. Sri Lanka had over 97,000 drug-related arrests in 2020 with 53% of arrests for heroin and 42% for cannabis including possession offences, according to latest data from state-run National Dangerous Drugs Control Board.
