The United States has warned its citizens of possible "imminent" attacks by militants on New Delhi, as the Indian police are put on high alert.

"There are increased indications that terrorists are planning imminent attacks in New Delhi," said a statement on the US embassy's website.
On Saturday, the Canadian and Australian missions in India followed similar warnings, cautioning their nationals against visiting certain parts of the country and avoid crowded shopping areas.
The new warnings suggest that a terrorist attack could be carried out in busy market places within the coming days or weeks.
The Indian Home Ministry says it is aware of the threats while the government has put its police force on high alert.
New Delhi has often blamed Pakistan's Inter-Services Intelligence (ISI) for aiding militant groups carrying out attacks in India. Islamabad has denied the charges.
The old rivals have a history of mistrust and have fought three wars since their independence from Britain in 1947.
