The Archaeological Survey of India has resumed the "scientific survey" to ascertain whether the Gyanvapi mosque was built over a pre-existing structure of a Hindu temple. The survey was stalled for a week and resumed with beefed up security on Friday. The Allahabad High Court gave permission for a scientific investigation and survey of the mosque on 25 August, saying that it was "necessary in the interest of justice" and would benefit both sides. The Varanasi court had previously ordered the ASI to survey the mosque on 21 July.
