From Yahoo! News - Gun-Wielding Fake Priests Kill Three:
"Two gunmen dressed as priests killed three men and wounded two others in a gangland shootout in the Bulgarian capital, police said Friday.
Assassins wearing the dark robes of orthodox priests gunned down a man linked to organized crime and two other men at a shopping center cafe in an affluent Sofia suburb and then fled, a police spokesman said.
'It was a shootout between criminal drug gangs,' the spokesman said, adding the assailants were still at large.
Police said one of the dead men was a close ally of a leading organized crime figure in Sofia and that the two other men killed alongside him appeared to be his bodyguards. "
