Israel sees serious threats to safety of travellers from the West because of anticipated terror attacks in India. Hence the travel alert.
But I guess other considerations will also have been taken into account. They could include the mayhem over the ban on big notes and rapes of tourists.
Rapes are a nightmare for tourists because almost no action is taken by the authorities and the victims have to make frequent visits to India to pursue cases.
That involves significant loss of time and money for them besides the perpetuation of the trauma.
