KUWAIT - A new round of Yemen peace talks scheduled to start on Monday in Kuwait has been delayed as some parties have not arrived yet, according to Kuwaiti officials.

Representatives of Yemen's Houthi group and former Yemeni President Ali Abdullah Saleh, both allied against a Saudi-led Arab coalition that backs Yemen's President Abd-Rabbu Mansour Hadi, have not left Yemen's capital Sanaa for Kuwait, Kuwaiti media officials said.

It is hoped that the United Nations-brokered talks would end more than a year of Yemen's civil war and a Saudi-led military intervention, which have claimed more than 6,400 lives, over half being civilians, and displaced millions, according to UN statistics.

A latest cease-fire kicked off on April 10 and was supposed to pave the way for Monday's talks, but both warring sides have complained of violation by the other side, including continued heavy shelling and air strikes.
