Palestinian activists said over the weekend that they would hold demonstrations in protest against US President Barack Obama's planned visit to the West Bank later this month.
A group called "Palestinian For Dignity" called for "huge demonstrations" against Obama and US policies "supportive of the occupation."
The group said that Obama was "persona non grata in Palestine" because of US military, financial and diplomatic aid for Israel.
"We call upon our people to demonstrate against receiving he who considers himself Israel's number one ally," the group said in a statement. "We also call for demonstrations against the idea of returning to the negotiations [with Israel."
