The government took steps Thursday to bolster security throughout the country to guard against possible terrorist attacks following the launch of the U.S.-led attack on Iraq.

The National Police Agency set up an emergency terrorism task force, beefing up security around U.S.-related installations and some 50 key infrastructure facilities, including nuclear power plants and airports.

In the largest security measures ever taken to counter possible terror attacks, the agency also ordered police forces to tighten security near landmark facilities and any place people congregate in large numbers.
