New Delhi: US ambassador to India Timothy J. Roemer on Wednesday said that his country wants Pakistan to bring those behind the Mumbai terrorist attacks to justice, including Jamaat-ud-Dawa chief Hafiz Saeed.

This matter, among others, will be discussed in greater detail between US President Barack Obama and Manmohan Singh, Roemer said, during Singh’s five-day visit to the US starting 22 November.

India and the US blamed the November 26-29 siege on Pakistan’s banned militant group Lashkar-e-Taiba (LeT).

The ambassador declined to comment on a US-China joint statement on Tuesday, which included a line of support for the improvement of India-Pakistan relations.

Describing the LeT as a global threat, Roemer said Pakistan should recognize the internal threat and dismantle the terror infrastructure existing on its soil.

He added that discussions on cooperation in counter-terrorism and issues concerning the situation in Afghanistan and Pakistan will be high on the agenda during the meeting between Singh and Obama on 24 November. The US would work “shoulder to shoulder, hand in hand and hour to hour" with India in preventing terror strikes, Roemer said.

The two leaders will also discuss the implementation of the civil nuclear agreement between them and related issues such as liabilities, licensing and reprocessing that are yet to be sorted out. “We are optimistic and pushing hard to see a successful completion of the agreement as soon as possible," the ambassador said.

Others issues for discussion would include climate change, education and a sustainable global economy.

Roemer also said India had not yet asked for the extradition of David Coleman Headley, a suspected LeT operative held in the US for plotting terror attacks in India.
