Yemen's warring parties failed to renew a U.N.-brokered truce deal that expired on Sunday, dashing the hopes of some Yemenis for a broader pact that would ease economic woes and prolong relative calm after more than seven years of fighting.
United Nations special envoy Hans Grundberg said late on Sunday he would continue to push for an extended and expanded deal between a Saudi-led coalition and the Houthi group, both under intense international pressure to come to an agreement.
