Six men accused of planning an attack on the Pope have been released and will not face any charges.

The street cleaners were arrested in London after allegedly joking about blowing up the Pope with a rocket-propelled grenade.

Terrorism investigators found nothing after searching the men's home.

Previous reports indicated the men were from North Africa, but police would not confirm that.

The Pope has wrapped up his four-day visit to Britain. The Vatican is calling the trip a success.
