Mumbai: US television studio ABC has apologised to Indian fans of its crime drama Quantico after an episode featuring Indian nationalists trying to frame Pakistan in a terrorist plot sparked online outrage against actress Priyanka Chopra, who plays a lead role in the show.

"The episode has stirred a lot of emotion, much of which is unfairly aimed at Priyanka Chopra, who didn't create the show, nor does she write or direct it," said Walt Disney-owned ABC in its statement.

After the recent Quantico episode, Priyanka has faced online attacks at home, and even some calls to boycott her work and the brands that she endorses, including Samsung Electronics Co.

Others called on the government to black out the scene where Priyanka, who stars as an FBI agent in the series, holds up sacred prayer beads as evidence that the plotter in the episode, planning to detonate a nuclear bomb in New York, was an Indian nationalist.

"The myth of Hindu terror, by a fake story, enters American television with the help of Priyanka Chopra. Would any Pakistani actress betray Pakistan or Islam the way she betrays India and Hinduism?" David Frawley, a Hindu scholar based in the US, tweeted.

ABC, in its statement, said Priyanka had no involvement in the storylines depicted in the series.

"The show has featured antagonists of many different ethnicities and backgrounds, but in this case we inadvertently and regrettably stepped into a complex political issue. It was certainly not our intention to offend anyone," ABC said in the statement.

Movies and popular culture have been under attack from Hindu nationalists in India in recent years. Earlier this year, a fringe outfit held violent protests and threatened actors over the release of Padmaavat, which showed a Muslim ruler pursuing a Hindu queen.

In 2016, online retail company Snapdeal was forced to drop actor Aamir Khan as its ambassador after backlash over his comments on intolerance in India.
