Jakarta, Sha'ban 5, 1435, Jun 3, 2014, SPA -- Two workers were killed Tuesday when a building they were constructing in Indonesia's East Kalimantan province collapsed, leaving at 13 buried, an official said. Rescuers using excavators sifted through mounds of concrete to find survivors after the unfinished three-storey commercial building collapsed Tuesday morning, said Mujiono, the head of the disaster management agency in the provincial capital, Samarinda. "Other workers who survived said there are 13 people still buried," dpa quoted Mujiono as saying. --SPA 17:23 LOCAL TIME 14:23 GMT www.spa.gov.sa/w
