Two people have been wounded in a bomb attack blamed on Tamil Tiger rebels outside a naval base near the Sri Lankan capital, Colombo, the army says.
The bomb exploded as a bus pulled up outside the Welisara navy camp, injuring the driver and a conductor.
Officials say the bomb, believed to be an anti-personnel mine, was intended to hit a naval convoy.
Violence between rebels and the army has escalated this year, with more than 200 people killed in the past month.
The navy camp targeted on Tuesday is close to a highway connecting Colombo with the country’s only international airport.
No group has said it carried out the attack, but the government pointed the finger at the rebels.
“It is obviously the work of the Tamil Tigers,” navy spokesman PDK Dassanayake told the AFP news agency.
“We are not sure if they targeted a civilian bus or were aiming at a navy vehicle. But they carried out the attack in a built up area risking the lives of civilians.”
The attack comes two days before the Sri Lankan government and the rebel leaders are due to meet for talks in the Norwegian capital, Oslo, to review their faltering ceasefire.
