( Sky ) - Security has been tightened around the Taj Mahal amid fears terrorists will strike as India celebrates 60 years of independence.
Police say there was a specific threat to attack the iconic "marvel of marble".
One senior officer added that India had sealed its border with Nepal, fearing Islamic militants will infiltrate the country and carry out suicide attacks.

" India cannot become a nation with islands of high growth and vast areas untouched by development," he said.
He also made reference to Mohandas Gandhi, the revered independence leader, saying: "Gandhi's dream of a free India will only be fully realized when we banish poverty from our midst."

India and Pakistan gained independence when the departing British split the subcontinent in 1947 and saw it quickly overshadowed by one of the most violent upheavals of the 20th Century.
Some 10 million people moved across borders in one of history's largest mass migrations as the states were divided into Muslim Pakistan and Hindu-majority India.

A year later Gandhi was assassinated by a Hindu fanatic.
