Many found humour in the situation:

Lots of people complaining about some smell in Karachi. It must be really terrible since they actually noticed it. Usually they're immune.

A Facebook page, named Weather Updates PK, claimed the smell was due to the easterly wind shift. The Somalian currents are very strong over the Arabian Sea and due to the presence of low-level circulation (LLC) off the coast of Karachi. As the wind reached towards the upper air levels, the city experience the weird smell. The Express Tribune could not independently verify the claims.
