Leading Pakistani human rights activist Ansar Burney, who fought for the release of Indian death row prisoners Kashmir Singh and Sarabjit Singh in Pakistani, was on Friday night deported from New Delhi back to Dubai, sources said.

Burney, who was the human rights minister in the interim government in Pakistan, was deported back from the Indira
Gandhi International Airport by an Emirates Airways flight at Airways flight at around 2030 hours because of a "look-out" notice against him, they said.

It was, however, not immediately clear who had issued the notice against him and in what connection.

Burney successfully secured the release of Kashmir Singh, who spent 35 years on death row in a Lahore [Images] jail, on February 20, 2008, as President Pervez Musharraf [Images] approved his mercy petition filed on the Indian's behalf by the human rights ministry.

Kashmir Singh was arrested in Rawalpindi on espionage charges in 1973 and was sentenced to death by an army court.

Burney is also playing a key role in efforts to save Sarabjit Singh, who was charged with triggering bomb blasts in Lahore in 1990, from the gallows.

It was his efforts that led to Pakistan government's indefinitely postponing execution of Sarabjiit earlier this month.
