A bomb has ripped through a bus being searched by soldiers at a military checkpoint in eastern Sri Lanka killing at least 15 people and wounding 10 others, the military said.
The bus was near the town of Ampara, about 220km east of the capital Colombo, when the blast went off on Monday, Brigadier Prasad Samarasinghe, a military spokesman, said.
At least 15 people were killed and 10 wounded, said Samarasinghe, who blamed the Tamil Tiger rebels for the attack.
The bus had stopped at a military checkpoint and most of the passengers descended from the bus while troops searched the vehicle.
As the soldiers were carrying out their search the bomb exploded, Samarasinghe said.
Ampara was the scene of bitter fighting last month between government forces and the rebels as the army fought to oust the rebels from bases they hold in the east.
There was no immediate claim of responsibility for the bombing.
The Liberation Tigers of Tamil Eelam rebels have fought the government since 1983 to create an independent homeland after decades of discrimination by the Sinhalese-dominated state.
The Tamil represent a 3.1 million minority in the north and east of the island. At least 69,000 people have died in the violence.
