ADEN: Yemen’s president has criticized what he called the “unacceptable” expulsion from Aden of hundreds of people originating from the north, after loyalists drove Iran-backed rebels out of the southern city.

“The individual acts of expelling citizens of Taiz and other cities (from Aden) is unacceptable,” President Abed Rabbo Mansour Hadi said late Sunday, quoted by the official sabanew.net website. Taiz, he added, was of strategic importance to Aden.

Prime Minister Ahmed bin Dagher said acts by “dozens do not necessitate in any case expelling hundreds” of northerners from the city, describing the move as “harsh collective punishment against a group of citizens.”

These acts were “unconstitutional and against “basic human rights.”

The UN special envoy to Yemen on Monday urged the country’s warring parties to make concessions to save peace talks aimed at ending a devastating 13-month war.

The appeal by Ismail Ould Cheikh Ahmed came after face-to-face talks broke off with the government delegation complaining of a lack of progress and the Iran-backed Houthi rebels protesting about air raids by the Saudi-led Arab coalition.

“The participants in the Kuwait negotiations must reflect the aspirations of the Yemeni people. I am confident that Yemenis want an end to the conflict,” he said in a statement.

Meanwhile, airstrikes by the Saudi-led, US-backed coalition have killed at least 10 rebels.
