With global attention on Yemen focused on a fragile truce in its main port of Hodeidah, fighting between rival forces in the country's four-year war has surged elsewhere.
Nine civilians were killed and at least 13 wounded earlier this week in attacks in the provinces of Hodeidah and Hajjah in war-torn Yemen, the UN said on Friday.
The UN special envoy to Yemen on Monday said the urgency of accessing grain stores trapped in a frontline position in the port city of Hodeidah was increasing as the food was "at risk of rotting".

A second round of negotiations between Yemen's government and Houthi rebels could be hosted "soon" in Jordanian capital Amman, a rebel leader said Sunday after meeting the UN envoy.
Yemen's flashpoint city of Hodeidah was calm on Tuesday following heavy clashes that erupted after the UN-brokered ceasefire started at midnight, pro-government sources and residents said.
Air strikes and fierce clashes shook the outskirts of Yemen's rebel-held port city of Hodeidah overnight, pro-government sources and residents said Sunday, despite a UN-brokered ceasefire.
