Arab League urges recognition of Palestine after Trump's Jerusalem decision
They also said they would head to the United Nations Security Council for a resolution condemning the US decision as a violation of international law.
In the occupied Palestinian territories, a total of four people have now been killed and dozens wounded since Trump announced the move.
The announcement drew criticism from every other member of the UN Security Council at an emergency meeting on Friday.
Palestinian Authority president Mahmoud Abbas has cancelled a scheduled meeting with the US vice-President Mike Pence in Ramallah later this month.
In Egypt, which Pence will also visit, the country's top Muslim and Christian clerics have both cancelled scheduled meetings with Pence in protest at the decision.
US President Donald Trump's decision "did not take into account the feelings of millions of Arab people", the Coptic Church's spokesman said in an online statement.
There have been fears of a much larger escalation of violence after Hamas leader Ismail Haniyeh called for a new Palestinian intifada, or uprising.
Hamas and the smaller Islamic Jihad militant group both renewed that call on Saturday.
Abbas' Fatah organisation urged Palestinians to "keep up confrontation and broaden it to all points where the Israeli army is present" in the occupied West Bank.
Israel seized East Jerusalem in the 1967 Six-Day War and later annexed it in a move never recognised by the international community.
East Jerusalem is considered occupied Palestinian territory under international law.
