She said she was deeply touched to meet the staff of both the hotels and 'to pay respect to the large number attacked.

'This hotel in this city suffered grievously and endured painful losses because of the extremists and violence visited on it.

'The great men and women who worked in this hotel and elsewhere in the city... (facing) senseless violence and helped save lives... they deserve our gratitude.'

She underlined that the American people stood in solidarity with the people of India when the November terror attack unfolded on TV screens.

And referring to Friday's terror bombings in Jakarta, Clinton said it was a 'painful reminder (that terrorism) is global, it is ruthless, it is nihilistic, and it must be stopped'.

Clinton will fly Sunday to New Delhi where she said she will meet government leaders for discussions on the issues including economic growth, climate change, education, health care, non-proliferation and counter-terrorism.
