UNITED NATIONS - Yemen's president told the United Nations on Monday that he has asked the Saudi-led coalition to begin a 7-day ceasefire on Dec. 15 to coincide with UN-sponsored peace talks aimed at ending months of fighting that have killed nearly 6,000 people. 'I informed the coalition's leadership that we intend to start a ceasefire for 7 days, from December 15th to 21st, in conjunction with the consultations,' President Abd-Rabbu Mansour Hadi said in a letter to UN Secretary-General Ban Ki-moon, excerpts of which were seen by Reuters. 'It will be renewed automatically in case of compliance from the other side,' Hadi said.
