Two bored 15 year-old students faced the full wrath of the CIA after sending phoney death threats via email to President Dubya.

The boys had used faked email addresses to avoid detection, a ploy that bought them a couple of days grace. However, as soon as the CIA managed to trace the source of the "terrorist threat", to a secondary school in Staffordshire, they asked Special Branch officers to investigate.

Special Branch visited the boys at their homes, and established that the boys had sent the mails as a joke.

Bowman told the Mirror that it appeared to be a prank gone awry. Although the boys escaped suspension, they have been given "a good talking to," she said.

The CIA said that it took all threats to the President very seriously.

The emailed messages also included what have been described in the press as "lewd" references to the president's daughters, Jenna and Barbara.

This is not the first time that the twins have been the butt of smutty jokes. Last week it was revealed by the New York Post that creators of the indiscriminately-offensive cartoon Southpark have had to scrap story lines involving the girls in their new show "That's my Bush," a take off of the first family.

Originally the twins were to be portrayed in the satire show as "sisterly lovers". However, once the plans were made public Comedy Central was blasted with emails demanding that the show leave the girls alone.

President Dubya himself warned the network that his daughters were not to be used in the satire, adding "And I mean that." ®
