B92 is reporting that a letter was received, sent as a fax from an unlisted Belgrade telephone, to Alternativna televizija Banja Luka, purportedly from the fugitive Radovan Karadžić. There is no confirmation of authenticity, and it may well not be authentic. There is also no sign of it on ATV's web site, at least not yet.
The content of the letter seems to be largely a complaint about OHR's measures in Republika Srpska, and a criticism of SDS for not responding decisively enough.
"Now it is to be or not to be," the letter tells citizens. I'll take "not to be" for 200.
