Wanted Arab terrorist Naif Hassan Omar Zaid was found dead at the Palestinian Authority (PA) embassy in Bulgaria, local media reported Friday morning.
His family confirmed to Palestine News Network that he was "assassinated" at the embassy in Sofia, the capital of Bulgaria.
Zaid, 51, was convicted of murdering yeshiva student Eliyahu Amadi in Jerusalem's Old City back in 1986, when he was 22 years old.
He was sentenced to life in prison, but was able to escape jail while being transferred to hospital during a hunger strike, and has been living in Bulgaria for the past 22 years. Israel demanded Bulgarian authorities extradite him in December.
Zaid is a member of the Popular Front for the Liberation of Palestine (PFLP) Marxist terrorist organization.
On Friday morning the PFLP claimed that the Mossad had assassinated Zaid.
Palestinian Authority leader Mahmoud Abbas published an official statement of condemnation, calling to establish an international investigative committee to clarify the circumstances of Zaid's death.
