An appeals court on Thursday upheld the conviction of an Israeli man sentenced to five years in prison for carrying out a bomb attack outside a Prague casino in a failed attempt to kill its Israeli owner. Yakov Moshaylov was found guilty of having thrown a bomb under a car in front of Prague's Casino Royal in August 2004. The blast lightly injured 18 people, most of them foreign tourists. The target of the attack, Assaf Abutbul, who owned the casino, was not injured and left the country a few days later. Czech police said a settling of scores between two criminal gangs was the most likely motive for the attack.
