Varanasi, Uttar Pradesh: The Archaeological Survey of India (ASI) today resumed its scientific survey work at the Gyanvapi mosque in Varanasi to determine whether the 17th-century mosque was constructed over a pre-existing structure of a Hindu temple. Government counsel Rajesh Mishra, who accompanied the ASI survey team during the day-long exercise a day before, on Saturday said the team started work in the morning and it would end at 5 pm. The Supreme Court on Friday refused to stay the Allahabad High Court order on the ASI survey of the Gyanvapi mosque, an exercise that the Muslim side says will "reopen wounds of the past".
