Security Tightened around Parliament

While walking over to listen to music last evening, we noticed that the road near Parliament was closed and new barriers were being put in place. Later I spotted an article in the evening paper that stated that "Security Tightened around Parliament"

"The anti-terror barriers around Parliament were today being upgraded to prevent a lorry bomb attack by terrorists. The road layout outside is also being changed to reduce traffic to one lane in each direction, with the security barrier due to be extended out away from the Lords. Fears of a vehicle-borne bomb attack in London have grown following the failed car bomb bids in the capital and at Glasgow airport last month."
