The interior minister said India 'cannot go back to business as normal'
The Indian government has announced a number of steps to strengthen internal security after the Mumbai attacks.
Interior Minister P Chidambaram said a national investigative agency would be launched, anti-terror laws beefed up and coastal security strengthened.
It is the government's first detailed response to the public outcry over the attacks which left at least 173 people dead, including nine of the 10 gunmen.
India says militants had Pakistani links and has urged Pakistani action.
Pakistan denies any involvement in the attacks, but has promised to co-operate with the Indian investigation.
It has been under tremendous Indian and American pressure to act.
The new Indian security plans were announced on the day a magistrate extended policy custody of the lone surviving gunman, Mohammed Ajmal Amir Qasab, until 24 December.
Challenge of terrorism
"We cannot go back to business as usual. We have to take hard decisions and prepare country and people to face the challenge of terrorism," Mr Chidambaram, the newly appointed Indian interior minister, told parliament.
