Bulgarian authorities are investigating the death of a Palestinian, wanted by Israel for a 1986 killing, inside the Palestinian Authority's embassy in Sofia.

The embassy identified the dead man as Omar Nayef Zayed, a Palestinian who took refuge in the embassy late last year fearing extradition to Israel.

The Bulgarian prosecutor's office said it was told by the embassy Friday morning of a death resulting from violence on the territory of the embassy. The Palestinian ambassador granted access to the investigators, it said, adding that the cause of death has not been established yet.

Zayed, 52, escaped from Israeli custody 25 years ago and has lived in Sofia since 1994. He was convicted of the murder of an Israeli man in Jerusalem's Old City and given a life sentence.
