A roadside bomb suspected to have been planted by Tamil Tiger rebels killed two police commandos on Thursday while Sri Lankan troops captured a rebel base in the north west, the military said.
The capture of the rebel camp in Mannar comes a week after one of the bloodiest battles in the country's long civil war in the same area.
"Advancing troops...brought the entire area under control on Wednesday," a spokesman at the Media centre for National security said.
The military said a suspected rebel roadside bomb in central Anuradhapura killed two police commandos, while police retaliation killed two rebels.
The military said fighting in the far north a day earlier, killed 25 Tamil Tiger rebels and injured 37 while four solders died and 14 were injured.
Fighting between government forces and the Liberation Tigers of Tamil Eelam (LTTE) has intensified since the government formally pulled out of a 6-year-old ceasefire pact in January, though a renewed civil war has been raging since 2006.
