COLOMBO , Sri Lanka ( CNN ) -- Colombo has been hit by a second bomb blast in only 24 hours following the fall of the Tamil Tigers ' capital to government troops . Police and army officials at the site of a suicide bombing in Sri Lanka 's capital Colombo Friday . Two people were wounded and a store damaged in the Petard commercial district Saturday . A day earlier a suicide bomber on a motorcycle blew himself up outside an air force headquarters in Colombo , killing two air force police officers and a member of the bomb-disposal unit . Another 30 people were injured . The attacks come after President Mahinda Rajapaksa urged the Tigers to lay down their arms and end a quarter-century of civil war . He made his call after government troops retook the separatists ' capital , Kilinochchi . In a televised statement Friday evening , Rajapaksa called the recapture of Kilinochchi `` a victory against separatism . '' `` The time is not far off when people of the north can breathe freedom again , '' Rajapaksa said . He invited the Tigers -- who have fought for an independent homeland for Sri Lanka 's ethnic Tamil minority since 1983 -- to surrender as government troops closed in on their last remaining strongholds . Rajapaksa 's announcement was met with fireworks in Colombo , and Friday 's news prompted celebrations in other cities as well . The Tamil Tigers ran a parallel administration from Kilinochchi with their own police force , courts , prisons and taxes , and they had declared government plans to retake the city a `` daydream . '' But after Sri Lanka launched a new offensive against the rebels in the fall , the insurgents moved their nerve center and logistics bases to Mullaitivu , on the northeastern coast . Sri Lankan troops have been on the outskirts of Kilinochchi , about 580 km ( 360 miles ) north of Colombo , for more than a month . They took a key highway junction and a town outside the city Thursday . The civil war has left more than 65,000 people dead . The U.S. State Department has designated the Tamil Tigers a terrorist organization .
