A Palestinian official has died after a confrontation with Israeli troops at a protest in the West Bank, reports say.
A Reuters news agency photographer said Ziad Abu Ein, a minister without portfolio, was hit and shoved by soldiers near the village of Turmusiya.
But Palestinian medics told the BBC that he died as a result of suffocation from tear gas that was fired.
Mr Abu Ein was rushed away from the scene in an ambulance, but died before reaching a hospital in nearby Ramallah.
The incident comes at a time of rising tensions in the region.
In recent weeks, 11 Israelis have been killed by Palestinians, including five who were stabbed and shot at a synagogue in Jerusalem. Twelve Palestinians have also been killed, among them several assailants.
