Prime Minister Manmohan Singh said on Tuesday that intelligence agencies had warned more terrorist attacks were likely, possibly on economic and religious targets as well as on nuclear installations.
"Concern about the increasing activities of externally inspired and directed terrorist outfits in the country is justified," Singh told an internal security meeting. "Intelligence agencies warn of a further intensification of violent activities."
Singh's comments came nearly two months after a series of bombs on commuter trains in Mumbai killed 186 people. The attack was blamed on Islamist militant groups with links across the border in Pakistan.
