Oscar-winning Pakistani documentary maker Sharmeen Obaid-Chinoy wants Pakistanis "to do their bit for fighting injustice".

Obaid-Chinoy, who made "Saving Face", said it was heartening to see so many people struggling to tackle the scourge of acid attacks and hoped their efforts would finally banish this curse.

"It is the responsibility of all Pakistanis to do their bit for fighting injustice, " Dawn quoted her as saying.

She said it was sad that acid attacks are under-reported.

Her film focuses on the work of Pakistani British plastic surgeon Muhammad Jawad, who travelled to Pakistan to perform reconstructive surgery on women who have been victims of acid attacks, mostly by their husbands.
