A man was jailed for 12 years on Tuesday for triggering an explosion in a Danish hotel while preparing a letter bomb to send to a Danish newspaper that had stirred controversy with cartoons of the Prophet Mohammad. Lors Doukaev, a Belgian citizen born in the restive south Russian region of Chechnya, was arrested on Sept. 10 after he accidentally set off a small blast at the Hotel Jorgensen in the centre of the Danish capital, injuring only himself. The Copenhagen court held that Doukaev aimed to send a letter bomb made of acetone peroxide, also known as TATP, to the daily Jyllands-Posten whose caricatures of the Prophet sparked Muslim furore and violent protests in 2005 in the Middle East, Africa and Asia.
