Violent clashes erupted at Negombo Prison in Sri Lanka, involving inmates from two drug‑related gangs. The fighting lasted two days and was described by Western outlets as the deadliest prison riot in the country in years.

According to reports from India and Qatar, at least 19 people were killed, while China and Western outlets reported at least 23 deaths. Other Indian and regional sources said the death count rose to at least 25, and another Western source put the figure at at least 26. Social media and Western commentary described the death toll as "dozens" or "more than two dozen."

Injury figures also vary. Chinese and Western reports said more than 100 people were injured; Indian and other outlets put the number at around 100, and an Indian source gave a specific count of 72 injured. A Times of India report stated that hundreds were injured.

The number of prison officials killed is likewise disputed. Other and Western outlets reported seven guards dead, Dawn reported six guards killed, and the South China Morning Post reported four guards killed.

Victims with cuts and gunshot wounds were taken to Negombo Hospital, according to Chinese, Pakistani and Western reports. The New York Times noted that Sri Lanka’s Special Task Force personnel were deployed outside the prison, and Dawn quoted Justice Minister Harshana Nanayakkara expressing profound shock and grief over the incident.
