The leadership said in a press statement that it has made intensive contacts to hold a UN Security Council urgent session to discuss putting an end to what described as "Israel's ongoing brutal offensive" against the Palestinians.
"We will also approach international organizations to protect our people," according to the statement.
The Palestinian leadership is composed of members of the Palestine Liberation Organization executive committee and members of the Fatah party's central committee.
"The Israeli escalation in the West Bank, which left five people killed and 400 others arrested, means that the Israeli government is pushing the situation towards explosion," the leadership warned.
The security situation in the West Bank has seriously worsened after Israel said three youngsters were kidnapped on June 12, Xinhua reported.
Hamas denied any connection to the abduction.
