Terrorism

Terrorism was the act of committing destructive acts with the purpose of spreading fear for political or religious reasons, participating individuals were known as terrorists.

On Earth

As a cover for alien invasion

Terrorism was used, both by governments and civilians, to explain away alien invasions which occurred on Earth in the late 20th century and early 21st century.

Black Thursday was the cover story issued by the British government to hide the true nature of the Nestene's attempted invasion of Earth in the 1970s. It was used to explain that the Auton shop window dummies coming to life and the resulting deaths that followed this incident were because of terrorists, which many citizens theorised were of the Irish Republican Army. (PROSE: Who Killed Kennedy, TV: Spearhead from Space) A later Nestene invasion (TV: Rose) which occurred on 5 March 2005 would be covered up in the same way. (AUDIO: One Rule)

As Gwen Cooper told Jack Harkness, Rhys Williams believed that occurrences such as the spaceship over London on Christmas Day and the Battle of Canary Wharf were the result of "sort of terrorism.", suggesting that they had put psychotropic drugs in the water supplies, resulting in mass hallucinations. Jack replied "Yeah, well your boyfriend's stupid." (TV: Everything Changes)

In 2008, when a fracturing of the Cardiff Space-Time Rift resulted in time slips occurring worldwide, initial news reports suggested terrorist involvement. When Rhys asked Gwen if she thought terrorists were responsible, Gwen replied "terrorists bomb things, this is different." (TV: End of Days)
