Almost a year and a half after 12 Danish cartoons of the prophet Muhammad sparked worldwide protest that left scores dead, Swedish cartoonist Lars Vilks has ignited similar controversy. After Mr. Vilks's controversial series of drawings featuring Islam's prophet with the body of a dog garnered attention in Sweden – art galleries refused to display them – Nerikes Allehanda, a Swedish newspaper, printed one in August. As with its Danish predecessor, the cartoon drew outrage from the Islamic world and has started a debate about freedom of expression. On Monday, the situation became even more serious, with Vilks going into hiding following a death threat from Al Qaeda in Iraq.
