India has increased security in major cities after receiving information that a Pakistan-based militant group is planning a New Year attack.
More police were deployed to city streets, including in the financial capital, Mumbai, which was attacked in 2008.
Airports and railway stations and the popular beach resort state of Goa all tightened security following intelligence reports that the banned militant group, Lashkar-e-Taiba was planning to target these places, a Home Ministry official said.
India has taken even minor terror threats seriously since a three-day terrorist siege killed 166 people in Mumbai, though there has been no major attack there since.
Security has been high in Mumbai since Friday, when police began searching for four men who authorities believe entered the city to carry out a terrorist attack. Computer-aided photographs of the four suspects were released.
Today police made house-to-house searches in some parts of the city and tightened security checks at bus and train stations, churches and markets.
In the 2008 attack, 10 armed terrorists fanned out across Mumbai attacking two luxury hotels, a Jewish centre and a railway station.
In March, Mumbai police said they prevented a major terrorist strike after they arrested two Indian men.
