A gunfight that broke out at Sri Lanka's largest prison has left at least 27 dead and 43 others injured, including a senior police officer.
It is the worst prison riot in the country in the last 30 years.
The maximum security Welikada prison finally called in armed troops Friday night, after police were locked in a gun battle with inmates for hours, Agence France Presse reported.
The clashes ignited after the Special Task Force (STF), Sri Lanka's elite police commandos, conducted a search for drugs and illegal mobile phones at the prison, Al Jazeera English reported.

Many of the injured have been admitted to the hospital for treatment, including 13 STF personnel, four soldiers and one civilian bystander, according to the International News.
Some of the prisoners had tried to escape during the fighting and were shot by security forces, according to AFP.
