Visiting European parliament president Martin Schulz has found himself at the centre of a political storm in Israel.
It concerns certain remarks he made during his address to the Israeli Knesset.
During his speech Schulz was heckled by members of a far-right party called Jewish Homeland.
Speaking in his native language things progressed well enough when the German politician expressed his support for a two state solution.
But later when he cited what he described as unverified data alleging Israel was denying Palestinians a fair share of water in the occupied West Bank, members of the pro-settler party walked out.
The leader of the party, Naftali Bennet later accused Schulz of spreading anti-Israel lies and demanded an apology.
Israeli premier Benjamin Netanyahu entered the fray in a separate parliamentary debate saying Schulz had been incorrect.
While Israel denies any water sharing disparity a a human rights group last month claimed Israeli settler towns were using three-an-a half times more water than Palestinians in the West Bank.
