New Delhi: India's state-run Press Information Bureau is facing online mockery after tweeting an edited image of PM Narendra Modi surveying deadly Chennai floods.

The bureau initially retweeted the prime minister's photo of himself looking through a plane window, with submerged fields and buildings visible.

Hours later, they tweeted the same image again, but with a much clearer scene crudely pasted on to the window.

The second tweet was deleted but not in time to prevent social media ridicule.

The PIB has made no public comment yet.

Mr Modi flew to Chennai in Tamil Nadu state on Thursday to see the damage caused by the widespread flooding, which has left more than 260 people dead since last month.
