United States Ambassador Robert Blackwill on Friday met Lok Sabha Speaker Manohar Joshi on the first anniversary of the December 13 terrorist attack on Parliament and assured that the US was with India in its war against terrorism.

After paying floral tributes to the martyrs who died on the fateful day, Blackwill reiterated his government's condemnation of the attack and also conveyed his deepest condolences to the family and friends of the deceased.

"What could be a more appropriate occasion than this to repeat with a full voice and a strong heart that India and the United States are together in the war against terrorism. That war will not be won until all terrorism against India and America ends permanently," Blackwill told reporters.

He recalled a statement made by the Bush administration a year ago that said "This brutal attack on the heart of Indian democracy is an attack on all democracies as well as an attempt to undermine the efforts of those seeking regional peace and stability."

Blackwill also quoted Congressman Tom Lantos of California in the House of Representatives on December 13 last year. Lantos had said that 'the attack against India, as with the attacks against the US, was not aimed at bringing down buildings'.

"They were cowardly attempts by terrorist organisations to attack free and democratic societies, to intimidate their people and their governments. India has waged a long battle against terrorism. I want to assure the people and government of India that they are not alone," he had said.

Blackwill said US President George W Bush had conveyed these sentiments when he telephoned Prime Minister Atal Bihari Vajpayee on the day of the attack.
