"The Department of State alerts US citizens to ongoing security concerns in India. The US government continues to receive information that terrorist groups may be planning attacks in India," the State Department said.
Terrorists and their sympathisers have demonstrated their willingness and capability to attack targets where US citizens or Westerners are known to congregate or visit.
Cautioning that the Mumbai attacks were a vivid reminder that hotels, markets and other public places are especially targeted by terror groups, the State Department asked its nationals to always practise good security, maintain a heightened situational awareness and a low profile.
"US citizens are advised to monitor local news reports and consider the level of security present when visiting public places, including religious sites, or choosing hotels, restaurants, entertainment and recreation venues," it said.
A month back also, the US, apprehending a Mumbai-type terrorist attack in various parts of India, had alerted its citizens to be cautious during their visit to the country.
