In India's big cities, though, the odds of being hit by a car are much higher than those of being a victim of a terrorist attack, McIndoe says. Other risks — health, crime, fire and, food and drink safety — are also greater than terrorism, he says.
The State Department, however, says that more than 600 people have been killed in terrorist attacks in major Indian cities since October 2005, including four large-scale bombings or attacks this year.
Besides last month's attacks, there were seven simultaneous attacks on commuter trains in Mumbai in July 2006. In New Delhi, several markets were bombed or attacked this past September and in October 2005. Explosives also were detonated on a train northwest of Delhi in February 2007.
"Multiple, simultaneous bombings in crowded public places in India over the past three years represent an increasing threat to American citizens traveling to India," the State Department says in its current report on India.
It advises Americans in India to "vary their routes and times in carrying out daily activities." But it also says it's "becoming more difficult to modify one's behavior to lessen the growing risk," because terrorists have targeted hotels, trains and stations, markets, cinemas, mosques and restaurants in large urban areas.
