United States President George W Bush [Images] has condemned the deadly series of bomb blasts in Delhi and said the "heinous" attacks have yet again showed that terrorists were enemies of humanity.

Joining a host of world leaders in deploring the attacks, Bush said, "By targetting innocent civilians making final preparations for holiday celebrations, terrorists have demonstrated yet again that they are enemies of humanity and contemptuous of the values all the civilised world shares.

"The United States strongly condemns the heinous terrorist attacks in India," a statement issued by the president's press office Sunday said.

"On behalf of the American people, the president extends his deepest condolences to all of those who lost loved ones," it added.

Fifty-nine people were killed and 210 injured when three near simultaneous explosions tore through two crowded markets and a bus in Delhi on Saturday evening.

Terming the attacks a "cowardly act", US Secretary of State Condoleezza Rice [Images] had Sunday said that terror knows no borders and respects no religion.

"Fighting terror is our common struggle, and we stand with the people of India as they bring to justice those responsible for these cowardly acts."
