Indian authorities have imposed restrictions on movement and gatherings in the part of the disputed Kashmir region under its control following the announcement of the death of anti-New Delhi Kashmiri leader Syed Ali Gilani.

The Indian authorities deployed dense units of police and armed soldiers in the city to prevent the funeral from turning into an anti-India protest. Soldiers with automatic rifles blocked the streets and the main road leading to Gilani's residence, while armored vehicles toured the city's neighborhoods.

Syed Ali Gilani - a prominent Kashmiri leader and one of the fiercest critics of Indian rule in the disputed region of Kashmir - died late Wednesday night at the age of 92.

Gilani, considered a symbol of resistance against India for the past three decades, died surrounded by his family in his home in Srinagar, the summer capital of Jammu and Kashmir, where he was under house arrest, his spokesman said on Twitter.

From the mosque next to Gilani's house, he called on the residents to stay in their homes, but dozens of armored vehicles and trucks roamed the streets of the area and the police asked people not to go out.

In turn, Pakistani Prime Minister Imran Khan said on Twitter that he was "deeply saddened by the death of Gilani, the leader who fought all his life for his people and their right to self-determination".

Gilani, who opposes the Indian presence in the disputed Muslim-majority region in the Himalayas, divided between India and Pakistan since 1947, has been under house arrest for 11 years, and has been ill for months.

Gilani has fought for the integration of Indian Kashmir with the Pakistani side since the 1960s, and spent 10 years in prison starting in 1962.
