Palestinian president Mahmoud Abbas has ordered an investigation committee to go to Bulgaria immediately and probe the circumstances of the death.

Bulgarian authorities are investigating the unexplained death on Friday of a Palestinian, wanted by Israel for a 1986 killing, at the Palestinian Authority’s embassy in Sofia.

The embassy identified the dead man as Omar Nayef Zayed, 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 on 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.

Bulgarian prosecutor General Sotir Tsatsarov said the body was found outside the embassy by a Palestinian embassy staffer as he parked his car. Zayed was still alive when an ambulance arrived, and there were no gunshot wounds. He died at the scene before paramedics were able to take him to hospital.

Mr Tsatsarov suggested a possible cause of death was that he had fallen from the embassy building. The Palestinian militant group PFLP, however, reported that Zayed was shot in the head.

The death came hours after Bulgarian prime minister Boyko Borisov returned from a visit toIsrael and the Palestinian Authority where he discussed the extradition of Zayed with theIsraeli prime minister and senior Palestinian officials.

“I told all sides that our prosecution had received a request for extradition and now a court was to decide whether he will be extradited or not,” Mr Borisov told parliament.

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.

The official Palestinian news agency WAFA said Palestinian president Mahmoud Abbas has ordered an investigation committee to go to Bulgaria immediately and probe the circumstances of the death.

PFLP said Zayed was a member of their organisation, who together with his brother and another Palestinian had stabbed an Israeli in 1986 and had received a life sentence.

In 1990, Zayed was taken to hospital in Bethlehem following a hunger strike, and later escaped from the hospital, moving to several Arab countries before settling in Bulgaria.

Israel asked the Bulgarian justice minister in 2015 to extradite him and Bulgarian authorities called on him to surrender. He refused and sought refuge in the Palestinian Authority’s embassy in Sofia.

His brother, Ahmed Zayed, and the other Palestinian were among those released in a 2011 swap for an Israeli soldier, Gilad Schalit, who had been held by Hamas-allied militants in Gaza for five years.
