Australia and Britain on Thursday warned tourists of the increased risk of militant attacks in New Delhi, joining Canada and the US, which have urged foreigners to avoid parts of the Indian capital.
The United States said Wednesday it had information of a "specific" threat to half-a-dozen of the city's shopping areas and markets which it described as "especially attractive targets."
The Canadian government said on its website that an attack could be carried out "in the following days or weeks in market areas" of Delhi frequented by foreigners, specifically in the Chandni Chowk area in Old Delhi.
Following this new advice, the Australian High Commission in New Delhi said Thursday it "strongly" advised Australians "to minimise their presence in market areas of New Delhi."
The advisories were upgrades to previous general advice warning of attacks on prominent business and tourist locations such as Western-owned hotels.
A statement from the British High Commission on Thursday warned that "there are increased indications that terrorists are planning attacks in New Delhi."
In February, a bomb ripped through a crowded restaurant popular with travellers in the western city of Pune, killing 16 people, including five foreigners.
It was first major incident since the 2008 Mumbai attacks in which 10 Islamist gunmen launched an assault on multiple targets in India's financial capital, killing 166 people.
The last major attack in New Delhi was a series of bomb blasts in busy, upmarket shopping areas in September 2008 that killed 22 people and wounded 100 more.Reuse content
