Emir of Qatar, Hamad bin Khalifa Al Thani, opened the Arab League Summit conference on Tuesday. Al Thani called for the setting up a $1bn fund to protect the "Arabness of Jerusalem," though he acknowledged that past promises to aid the Palestinians have gone unfulfilled. "We are all obligated to work to defend Jerusalem, the Arab states must swiftly and seriously act," he said, adding that Qatar will contribute $250m to the fund.
