Dozens of Palestinian protesters have hurled eggs and shoes at the convoy of the visiting Canadian foreign minister.
John Baird is in Ramallah to meet his Palestinian counterpart Riad Malki.
Protesters also held signs reading: "Baird you are not welcome in Palestine."
Activists from Palestinian President Mahmoud Abbas's Fatah party earlier called for a boycott of Mr Baird because of Canada's perceived pro-Israel stance.
Mr Baird is in the region for five days of meetings with Israeli and Palestinian officials.
In a statement, Mr Baird described his meeting with Mr Malki as "cordial and constructive" and included "candid and frank exchanges on areas where we differ in opinion".
Canada is opposed to the recent Palestinian bid to pursue war crime charges against Israel.
