"My message is that if we are living in this kind of environment, we need an infrastructure that will cope with this," said Tata who added that the fatalities in the attack last week could have been minimized.

The terrorists were highly trained and used technologies such as satellite phones, global positioning systems (GPS) and maps from Google Earth, according to police.

The government has responded so far to criticism from the public by accepting the resignation on Sunday of the country's home minister, Shivraj Patil. But it is being seen as too little, too late. Patil's resignation has been repeatedly demanded after bombs planted by terrorists went off in Mumbai, Ahmedabad, and Bangalore earlier this year.
