U.N. chief opens Yemen talks, Saudi-led planes bomb capital

By Stephanie Nebehay and Tom Miles GENEVA (Reuters) - U.N. Chief Ban Ki-moon launched Yemen peace talks in Geneva on Monday with a call for a humanitarian truce as warplanes from a Saudi-led Arab coalition pounded the Houthi-controlled capital Sanaa overnight. More than 2,600 people have been killed since the coalition began military operations in March to stop the Iranian-backed Houthi militia moving on Aden and to shore up embattled President Abd-Rabbu Mansour Hadi, then in the southern city.
