At least 15 people have been killed and more than 32 injured in southern Sri Lanka when a powerful bomb went off inside a crowded bus.
It is the second such attack in two days. Yesterday, six passengers were killed and another 70 injured in an explosion on a bus near Colombo.
Today's blast occurred on a privately-owned bus travelling from Colombo to Matara, a distance of 160km along the main coastal highway.
The bus was driving along the tourist strip between Ambalangoda and Hikkaduwa when the bomb went off.
