Sri Lanka's military says it bombed Tamil Tiger positions in the country's north Saturday, a day after government troops seized the rebels' headquarters in Kilinochchi.
The military said it was moving farther into rebel-held territory, bombing the northeastern port town of Mullaitivu and other rebel strongholds.
Pro-rebel Web site Tamilnet said Sri Lankan forces also continued artillery shelling in the Vanni region Saturday. The report said the shelling has wounded many civilians.
Separately Saturday, authorities say a bomb planted under a vehicle exploded in the Sri Lankan capital, Colombo, wounding three people. Military spokesman Brigadier Udaya Nanayakkara blamed rebels for the attack, saying it was likely intended to create panic.
On Friday, a suicide bomber blew himself up in another area of Colombo, killing three people.
That attack followed President Mahinda Rajapaksa's announcement that the military had captured Kilinochchi after months of intense fighting.
The rebels acknowledged losing Kilinochchi but said they had moved their headquarters farther northeast before the town fell.
An ethnic Tamil lawmaker, Mano Ganesan, appealed for an end to the fighting today and called on the government to make more progress in seeking a political solution to the ethnic conflict instead of just focusing on a military victory.
Tamil rebels have been fighting since 1983, to establish an independent homeland for members of the Tamil ethnic minority in the island nation's north and east. They say Tamils are treated as second-class citizens by the Sinhalese majority. The civil war has killed more than 70,000 people.
The United States considers the rebels a terrorist organization but is calling for a peaceful dialogue to resolve what it considers to be the "legitimate issues of the Tamils."
