ISLAMABAD: Veena Malik, a Pakistani actress who posed in the nude for an Indian magazine with the initials of Pakistan's intelligence agency on her arm, has triggered fury across this conservative nation.

The photo on the website of FHM India, in advance of its publication in the magazine's December issue, has been lighting up social network website Facebook and Twitter since earlier this week.

Many here anticipate a backlash.

Malik has broken Pakistani social and national taboos in the past. She is a target for conservative ire and a heroine to some Pakistani liberals.

Conservative cleric Maulana Abdul Qawi declared on Aaj TV on Saturday that the latest controversy was a ''shame for all Muslims.'' Farzana Naz, interviewed by the same channel on the streets of Lahore, said that the actress had ''bowed all us women in shame.''

Twitter commentator Umair Javed however called on Pakistanis to ''make copies of the picture and bury it in your backyard. This way, our grandkids will know there were some amongst us who lived free!''

Asked by reporters whether Pakistan would ''pursue the matter'' legally, the country's Interior Minister Rehman Malik said Saturday, ''First, let us see whether it is real or fake.''

Malik for her part says that the photo at the root of the current uproar was published in violation of her agreement with FHM India.

In an interview with Pakistani Geo television broadcast Saturday, Malik acknowledged having been photographed for a ''bold but not nude shot.'' She said the editor of the magazine had promised that he would cover most of the photo with the ISI initials.

Malik said that the photo was intended to poke fun at the Indian fear of Pakistani spies: ''Whatever happens (in India), people say ISI is behind that.''

Malik said she would ''probably'' take a legal action against the magazine for violating terms and condition.

Magazine editor Kabeer Sharma said Malik did all with her full consent.

''We have all the record(s),'' he told the Pakistani television station. ''Veena was very excited about that ISI idea.''

Malik does most of her work in India. The entertainment sector there is booming, while Pakistan's is relatively moribund. Her ties to India have landed her in controversy in the past.

During a much-publicised talk show appearance early this year, she lashed out her nemesis Abdul Qawi, who criticised her for having a scripted love affair with an Indian actor on an Indian reality show.

''What is your problem with me?'' an angry Malik demanded of the scholar, who had accused her of insulting Islam.
