Palestinian President Mahmoud Abbas (C) prays next to the coffin of Palestinian minister Ziad Abu Ein during his funeral in the West Bank city of Ramallah December 11, 2014. Israeli and Palestinian officials issued conflicting accounts on Thursday over the results of an autopsy on a Palestinian minister who died after being shoved and grabbed by the neck by an Israeli policeman at a West Bank protest on Wednesday.A top Palestinian official, Hussein al-Sheikh, told Reuters that Jordanian and Palestinian doctors involved in the late night examination of the body said Ziad Abu Ein, 55, had died from "being struck, inhaling tear gas and a delay in providing medical attention." But an Israeli medical source familiar with the autopsy results told Reuters the minister died from a heart attack and had a pre-existing heart condition.
