NEW DELHI: Emergency workers pulled out three more survivors from the rubble of a collapsed building in southern India on Tuesday, as authorities said they expected to wrap up rescue efforts by the end of the day. While the death toll from Saturday’s disaster on the outskirts of Chennai rose to 26, officials said more than a dozen people were still believed to be trapped in the debris. Karuna Sagar, a senior officer with the Tamil Nadu state police force, said the three latest survivors were rescued overnight as hundreds of rescue workers toiled round the clock. “Three people have been pulled out alive. One late at night and two others early this morning. They have been taken to the hospital,” Sagar told Agence France-Presse by phone. “There may be another 15 to 20 trapped, but rescue efforts are in progress and going according to plan.” Sagar said that the number of people known to have died now stood at 26.
