US President Barack Obama said a good India-US relationship has to be based on mutual respect.

People in Agra would not be able to use their mobile phones for three hours on Tuesday when US President Barack Obama comes calling.

The Uttar Pradesh government has worked out a security plan for the visit and sent its top officials to the city to work along with US security officials to oversee arrangements and plug gaps, if any.

The entire stretch from Delhi to Agra would remain under high alert January 27 and for three hours people would not be able to use their mobile phones in the vicinity of the Taj Ganj area, the Mall road and the Fatehabad road as electronic jammers would be in operation, officials said.

The US security agencies are not willing to take any chances, sources said.

The entire route from the Kheria airport to the eastern gate of the Taj Mahal, and inside the complex, would be under the direct supervision of the US commandos.

They would also be keeping an eye from the rooftops of hotels and houses in the Taj Ganj area.
