   Bodies found in mass graves  Sarajevo (Reuter)- Investigators
said yesterday that they had exhumed 105 bodies from two mass
graves in north-west Bosnia. They are believed to be Muslims
killed by Bosnian Serbs at the beginning of the war, state radio
reported.  Bosnian investigators found 77 bodies at one site,
which they believe to be those of men from the village of
Velagici, near the town of Kljuc, killed on 1 June 1992, the
radio said. Investigators are still working on a second site, a
cave where 28 bodies were unearthed. They believe the cave
contains the bodies of up to 150 civilians from Biljani, also
near Kljuc.  In a separate development, United Nations
investigators have found 200 bodies in a mass grave near
Vukovar, Croatia. The victims are believed to be hospital
patients executed after Serbs seized the region in 1991.  A
spokesman for the UN transitional authority in Eastern Slavonia,
a Serb-held enclave due to revert to Croatian government rule
next year, said the bodies had been sent to Zagr
