Twelve aid agencies in the Yemeni town of al-Dhalea have stopped work after attacks on their buildings that the United Nations called an "alarming escalation" amid media campaigns against aid organisations.
The majority of attacks occurred overnight Saturday. One more occurred on an unoccupied Oxfam office on Tuesday morning, aid agencies said.
Among the agencies hit overnight on Saturday by rocket-propelled grenades (RPGs) fired by unknown individuals were Oxfam and the International Rescue Committee (IRC).
The attacks on Saturday wounded one person, damaged property and caused 12 organizations to suspend aid programs in al-Dhalea, affecting 217,000 residents, United Nations aid chief Mark Lowcock said on Monday.
Oxfam said their office was hit by two RPGs, but nobody was injured. Tuesday's attack used an improvised explosive device (IED).
IRC said its office and a women's centre were hit by RPGs on Saturday, injuring one security guard. "Aid workers are not a target. Those who will suffer the most are innocent Yemenis who benefit from IRC's ... work," IRC said.
Yemen has suffered from almost five years of conflict since the Iran-aligned Houthi movement ousted President Abd-Rabbu Mansour Hadi's government in late 2014. The coup drew military intervention in 2015 by a Saudi-led coalition trying to restore Hadi's internationally recognised government.

The southwestern province of al-Dhalea lies on the main south-to-north road linking the southern port of Aden -- controlled by Hadi's government -- to the Houthi-controlled capital, Sanaa. A contested frontline runs across the province.
"I urge a thorough investigation, and I express my appreciation to the Government of Yemen for the work they have begun in this regard. I also remain gravely concerned by the continuation of media campaigns in parts of Yemen that spread rumours and incitement against aid operations," Lowcock said.
Yemen's war has killed thousands and pushed millions to the brink of famine. Around 80% of the population needs humanitarian assistance.
