At least 20 workers were feared killed in a landslip in a granite quarry in the southern Indian state of Andhra Pradesh on Thursday, reported Indo-Asian News Service on Friday. The deadly incident took place in the Prakasam district of Andhra Pradesh, where police said two bodies were recovered late Thursday while two injured people were shifted to hospital. The work to clear the debris was still on, according to the report. Over 20 people were working 60 to 80 feet deep in a granite quarry when huge boulders from the edge of the quarry fell on the workers. Authorities face a tough task in clearing the debris as heavy cranes could not reach the scene due to lack of proper roads, said the report.
