Dozens of protesters gathered outside the US embassy in Jordan's capital, Amman, on Thursday, the day before President Barack Obama's visit to the kingdom.
Protesters chanted their opposition to Obama's visit, and to Washington's policies on Israel, which are widely seen as biased in favour of the Jewish state, and which fall short of meeting Palestinian aspirations for statehood and independence.
Obama is on his first visit to Israel and the West Bank, and only his second to the Middle East, not counting a quick trip to Iraq, since taking office.
"This stand is just to pass a message to Obama that he has maybe the last chance, because this is his second round in the White House, to make just peace in Palestine," said one protester, Lina Nafie.
"Yesterday we listen to his talk, his talk is ok but he doesn't do anything on the ground."
In a speech in Jerusalem to the Israeli people earlier on Thursday, Obama said Israelis and Palestinians each had rights to peace, security and free movement that are not always respected.
He went on to say Palestinians have a right to self-determination and justice that must be recognised.
On Friday he will be making his first trip to Jordan as president.
Peace talks between Israel and the Palestinian Authority, developments in Syria, and Iran are Obama's main focus.
