The US, Australia, Canada and Britain warned Saturday that terror groups were likely planning “imminent attacks” in India's capital and foreigners there should be vigilant. “There are increased indications that terrorists are planning imminent attacks in New Delhi,” the US embassy said in a statement on its website, urging tourists to avoid half-a-dozen of the city's popular shopping areas. Police in New Delhi were taking “appropriate measures” in response to the warnings, said police spokesman Rajan Bhagat as a source said police had been put on alert. “Security is adequate,” Ravindra Singh, spokesman for India's Ministry of Home Affairs, said. The Canadian travel warning said that “credible and specific reporting indicates that a terrorist attack could be carried out in the following days or weeks, in market areas of Delhi frequented by foreigners.” It echoed a warning for Australian travelers to “exercise a high degree of caution” in India in general and to avoid crowded shopping areas in the capital. Local police said they were aware of the warnings of possible attacks. Britain issued similar warnings. The US advisory said markets in New Delhi such as Connaught Place in the heart of the city could “be especially attractive targets for terrorist groups.” “Specific and credible information indicates terrorist attacks in New Delhi, especially in markets, may be imminent,” the Australian High Commission (embassy) said. The latest terror warnings come as India battles to assure visitors it can serve as a safe host for the Commonwealth Games slated to be held in October in New Delhi, which has been targeted before by militants. Security concerns about the forthcoming Commonwealth Games were stoked in April when two low-intensity bombs went off at a cricket stadium.
