New Delhi: External affairs minister S.M. Krishna on Monday ticked off his junior minister Shashi Tharoor for publicly questioning new visa guidelines, saying if he had any “perceptions", those should be discussed within the “four walls" of the government.

While tweeting, Tharoor wondered whether tightening of visa norms for foreign nationals made any sense at all and if it would actually “protect" security.

Contending that “26/11 killers had no visas", the minister of state for external affairs had asked whether India would allow terrorists to make it a “less welcoming" destination.

Under the new rules, any foreign national holding long-term multiple entry visas will have to take a two-month break before re-entering India. However, this was amended later, with government saying exception would be made for bona fide travellers if they submit itinerary details.
