Think about the context before applying such bold judgement though.
The Indian paper had likely touted this story of "indigenous Afghanistani drone development" (as a Bollywoodised exaggeration) in order to very deliberately accentuate and publicise the "industrial capabilities" of the Talibs, such that they may be publicly brandished as a proud asset against Pakistan's western border and even, ostensibly, to scare us.
This is consistent with the usual chest-thumping modus operandi from the hindutva mob to our east. They have made Talibs their asset and will publicise them wherever possible, sometimes in exaggerated fashion.
This is a fine example of Delhi mouthing off uncontrollably to the point that their asset paid the price for such publicity. Talibs have much to learn about the Indian addiction for publicly revealing sensitive intelligence as their best hope for "premature psychological victory".
The source should not be automatically expunged because of its origin but rather, the context should be considered in order to determine its likely veracity.
