Defense Minister Moshe Ya’alon said in a statement on Wednesday that the death of PA minister Ziad Abu Ein is under IDF investigation.
An offer to conduct a joint investigation was extended to the Palestinian Authority, Ya'alon said and that the parties were expected conduct an investigation together on Abu Ein's body.
Ya'alon emphasized the importance of continued stability and security in the region, and said that coordination with the PA will continue. 
Earlier on Wednesday, Palestinian Authority President Mahmoud Abbas condemned the death who died shortly after clashes with Israeli troops, threatening to halt security coordination with Israel.
Ziad Abu Ein, a PA minister without portfolio, was rushed by ambulance from the village of Turmusiya after being hit and shoved by IDF soldiers during a protest on Wednesday, according to a Reuters photographer who witnessed the incident and a medic.
The man died en route to the nearby city of Ramallah. Israeli army sources believe his death was a result of a heart attack and said it was looking into the incident.
Abbas called the death of Abu Ein a "barbaric assassination'" that would not be tolerated.
