(Reuters) – United Nations Secretary-General Ban Ki-moon met Saudi Arabia’s powerful deputy crown prince on Wednesday and the pair discussed improving civilian protection in Yemen after a U.N. report briefly blacklisted a Saudi-led coalition for killing children. Ban removed the coalition from the blacklist earlier this month pending review after Riyadh, a major U.N. donor, threatened to cut Palestinian aid and other U.N. funding. Saudi Arabia has denied using threats, although Ban blasted Riyadh for exerting “unacceptable” pressure.
