A major gunfire was reported in the Saindamarathu area, in Kalmunai, when the security forces attempted to raid a safe house occupied by extremists. 

This was the first gunfire that took place between Sri Lankan security forces and extremist militants. 

Police sources said several explosions were heard from the safe house. However, it is not immediately clear whether the militants have blown themselves up or exploded their devices. 

Sources on the ground confirmed several casualties. However, official spokesperson of the Army and the Police are yet to release official numbers. 

The Police have announced indefinite curfew in Samanthurai, Kalmunai and Chawalakadai Police divisions.
