Palestinian Authority minister Ziad Abu Ein reportedly died after he was assaulted in clashes with the Israeli Defence Forces during a protest in West Bank on Wednesday.
The minister was "hit and shoved" by the Israeli forces, according to Reuters.
According to Al Jazeera, Abu Ein died from inhaling large amounts of tear gas used by the Israeli troops on protesters in Turmusiya.
However, protesters said he was brutally assaulted by the Israeli troops.
A Palestinian security source told AFP that Israeli troops assaulted Abu Ein with the butts of their rifles and their helmets.
Palestinian President Mahmoud Abbas called the incident a "barbaric act which we cannot be tolerated."
Israelis and Palestinians have been involved in a series of skirmishes over the recent months that have raised the tension of another war months after the Gaza conflict earlier this year left hundreds dead.
"The fact that a member of the government has died will further inflame the situation," Al Jazeera reported.
