Pakistan has proposed a joint investigation with India into the deadly attacks on Mumbai as Indian officials demanded Pakistan hand over suspected militants living in the country.

Meanwhile, the Indian government said it was not considering military action in response to the co-ordinated attacks on 10 targets in Mumbai, which claimed the lives of at least 172 people.

Two Canadians from Montreal, Dr. Michael Moss and his partner, Elizabeth Russell, died in the attack.

"Nobody is talking of military action," Foreign Minister Pranab Mukherjee told reporters when asked about options on what action could be taken.

But tensions between the rival nuclear powers have intensified since the attacks as Indian officials have blamed the siege on Lashkar-e-Taiba, a Pakistani militant group with links to the disputed region of Kashmir.

The only surviving attacker has told police that the 10 gunmen had trained for months in camps operated by the banned group.

In an apparent attempt to cool down the rhetoric, Pakistani Foreign Minister Shah Mehmood Qureshi called for a joint investigative mechanism with India to look into the attacks. It is not yet known if India responded.

India has demanded that Pakistan hand over suspected militants believed to be living in the country, including Dawood Ibrahim, the alleged mastermind of the 1993 Mumbai bombing and India's most-wanted man.

It is also seeking Masood Azhar, a suspect freed from an Indian prison in exchange for the release of hostages aboard an Indian Airlines aircraft hijacked on Christmas Day 1999.

A list of about 20 names was given to Pakistan's high commissioner to India during a meeting Monday night, India's foreign minister told reporters.

On Tuesday, Pakistan said it has to first examine the Indian demand.

"We have to look at it formally once we get it, and we will frame a response," Information Minister Sherry Rehman told reporters in Islamabad.

India's demands come as the government has faced widespread criticism for security lapses and intelligence failures over the Mumbai siege.

The Associated Press reported that India's foreign intelligence agency received information as recently as September that Pakistan-based militants were plotting attacks against Mumbai targets, according to a government intelligence official familiar with the matter.

The information was then relayed to domestic security officials, the official said. It is no known what the government did with that intelligence.
