MUMBAI: After ghazal maestro Ghulam Ali, Hindu extremist organisation Shiv Sena has asked management of a city-based convention centre here to call off former Pakistani foreign minister Khurshid Mahmud Kasuri's book launch function.

Citing the neighbouring country's support to terrorism as the reason behind the opposition, the party warned that the function will be disrupted if not cancelled.

Sena vibhag pramukh Ashish Chemburkar submitted a letter to director of Nehru Planetarium here, demanding that the event be cancelled and organisers informed accordingly.

"The people at Nehru Planetarium where the event is scheduled, told us they will try to cancel it," Chemburkar said.

"We have informed them that we will disrupt the event if it is not canceled," he said.

The Observer Research Foundation Mumbai, which is organising the event, on Friday approached Maharashtra chief minister Devendra Fadnavis, seeking "adequate security" to Kasuri after cancellation of Ghulam Ali's concert in the city.

Kasuri will launch the book 'Neither a Hawk nor a Dove: An Insider's Account of Pakistan's Foreign Policy', in Mumbai on October 12 at the Hall of Culture, Nehru Centre, Worli.

During his stay in Mumbai between October 11 and 14, Kasuri, besides attending the book launch function, will also visit Mani Bhavan and Jinnah House "if possible", he said.

Kasuri will also meet veteran movie star Dilip Kumar at his residence.
