I am guessing they had to put pressure on India to come out clean, the DGMOs might not have spoken but some one did call in, else I just do not see PAF not putting out a retaliatory strike. There was little for us to go on, unless Indians explained that this was an accident.The most strange thing in the Press Conference of DG ISPR is that he categorically mention in response to a query that No contact b/w DGMo of both countries was made.
In my opinion this is potentially more dangerous than the crash of actual Brahmos inside Pakistan.
