ROUGH CUT - NO REPORTER NARRATION Sri Lankan police found explosives and exchanged fire with a group of men during a raid in the east of the country on Friday (April 26).
The raid took place in the town of Ampara Sainthamaruthu near Batticaloa in search for those responsible for the Easter Sunday suicide bombings that killed 253.
''A search found explosives used to produce bombs, IS uniforms, curtains with IS logo, 150 gelignite sticks, 100,000 metal balls and a drone camera from a house in Samanthurai," a spokesman said, referring to a separate search operation.
No details of casualties were immediately available.
Bombings police have been conducting raids across the country to find more details about the perpetrators and their supporters.
Nearly 10,000 soldiers were deployed across the Indian Ocean island state to carry out searches and provide security for religious centres, the military said on Friday.
Islamic State has claimed responsibility but provided no evidence to back its claim that it was behind the attacks.
If true, it would be one of the worst attacks carried out by the group outside Iraq and Syria.
