Dial down the temperature, flagging

"I had spoken to High Commission of Australia. That particular word apparently comes from an Australian newspaper headline and not from the comments of Australian Minister. Look we should think dial down the temperature on this. We are very concerned about the life and safety of Indians in Australia and particularly our students. We have urged them to please take sensible precautions, not to go to certain places in the dark, to know their routes, to travel in lighted areas, to travel in groups, all these advice have been issues by the ministry because we are concerned about the health, safety and wellbeing of our citizens," Tharoor said.

About 115,000 Indians have studied in Australia over the past 12 months, but attacks on members of the community have created fears that the country may not be a safe education destination.
India's Foreign Ministry has issued an advisory to its nationals studying in Australia, flagging "several incidents of robbery and assault" despite stepped up measures by police to confront the attacks. (ANI)
