When CNN asked sharif for evidence/proof sharif replied " Indian social media"
So till now this is the proof.
Yesterday CNN posted an article atleast a single Rafael shoot down as per their sources in french intelligence and from Dassault unofficial but all of these are only assumption no solid evidence.
Lastly have faith in Indian government. If any losses are there then govt will definitely share it with public.
Remember our defence forces don't hide casualties like others. Like in galwan clash, around 20 brave hearts martyred which was briefed by army while china hide their losses for years.
