Oxygen, food and water supplies running low and massacres taking place, says Nabil Shamsan

The Houthis are trying to send the city of Taiz back to the stone age, the city’s governor said in a briefing designed to urge the international community to do more to lift the month-long siege.

Nabil Shamsan said massacres were taking place in Yemen’s third city, that oxygen and water supplies were running out and that rubbish was piling up in the streets due to landfill sites being either full or inaccessible.
