Yemen's Houthis detain aid workers

At least 18 aid workers were kidnapped by Yemen's Houthi rebels in four rebel-held parts in Yemen, the Yemeni Mayyun Organisation for Human Rights said.

Ten workers were reportedly from UN agencies.

Yemen's internationally-recognised government condemned the "massive abduction campaign", saying it targeted "dozens of employees of the United Nations agencies, the office of the UN envoy Hans Grundberg and several international organisations working" in the capital Sanaa and other Houthi-run areas.
