The government has described the US embassy advisory on possible Al-Qaeda attacks in New Delhi and Mumbai as "very innocuous".
It, however, refrained from commenting on the presence of foreign terrorists in the country.
"It is normal for a mission to issue advisories whenever they have information. We too do the same thing. They do their security arrangements based on that. It is a very innocuous advisory," Union Home Secretary VK Duggal told a press conference.
He was commenting on the warning issued by the US embassy that Al-Qaeda and other foreign terrorist groups may carry out attacks in the Capital and in Mumbai ahead of or during the Independence Day.
The embassy said that the attacks could possibly occur from Friday till August 16 and the likely targets were airports, vital government installations and crowded places.
The warning came a day after a major terror plot was foiled in Britain.
Duggal repeatedly ducked questions on whether there was any presence of Al-Qaeda in the country. "I have only seen the advisory and there is no intelligence input shared with us.
"It is normal for them to issue advisories for their mission staff to maintain a low profile. This is strictly their internal matter. I have no comments whatsoever," he said.
Duggal said that the exercise was similar to the action the Centre takes whenever it gets an intelligence input.
"We handle it in an appropriate manner. We sensitise all concerned agencies, state governments, and keep reinforcements ready. It is the job of the government and home ministry to do their best to provide security and safety to the people and citizens of the country," he said.
Ahead of the Independence Day, he said, every possible measure had been put in place to thwart attempts by Pakistan-based terrorist groups to unleash terror in the country.
Delhi Police had on Thursday night arrested two LeT terrorists at New Delhi railway station.
