COLOMBO, January 16, SPA -- A roadside bomb tore through a Sri Lankan bus killing 24 people and wounding dozens on Wednesday, officials said, as a 6-year ceasefire formally expires between the government and Tamil Tiger rebels, Reuters reported. The Ministry of Defense said a large number of schoolchildren were on the bus at the time of the blast in the central district of Moneragala, around 150 miles east of the capital Colombo. However, hospital officials said they were treating only four children for minor injuries, and that no children were killed.--SPA www.spa.gov.sa/518096
