Yemen's Houthi group hit a Saudi oil tanker off the main port city of Hodeidah on Tuesday, the Saudi-led coalition said, in an attack that could complicate a new United Nations push to end a war that has killed more than 10,000 people.
"Humanitarians must be able to reach the people who need help the most, without conditions", Guterres said.
The United Nations hosted a donors' conference in Geneva today (Tuesday) to raise funds to address humanitarian crisis in Yemen. Hodeidah is Yemen's biggest port where most of the humanitarian aid enters for millions of hungry civilians but the government accuses Houthis who control the port of smuggling weapons through it. Mekhlafi said: "We need to find the ideal solution which is a return to the talks table, to put an end the war, to return to a sustainable system supported by the people of Yemen, including the putschist parties and those supported by the global community".
The coalition repeatedly denies it has committed war crimes in Yemen, and its investigations have been slammed by human rights campaigners as not credible.
The war has killed more than 10,000 people, displaced more than 2 million and driven the country to the verge of starvation.
The Iranian-aligned Houthis said they had targeted a coalition warship in response to an air strike on Hodeidah on Monday that killed at least a dozen civilians, including seven children. Saudi Arabia, along with the United Arab Emirates, has bombed and killed Yemen's Iran-allied Houthi rebels in addition to thousands of civilians.
According to the WSJ report, the consulting company briefed top Emirati national security officials on two occasions, and experts involved in the making of the war game were unaware of who the client was.
Asked if he saw a contradiction in the Saudi stance towards Yemen, Guterres said a country s humanitarian commitments and military actions should be kept separate.
The Saudi aggression was launched in March 2015 in support of Yemen's former Riyadh-friendly government and against the country's Houthi Ansarullah movement, which has been running state affairs in the absence of an effective administration.
After more than one million Yemenis were found with apparent cholera a year ago, World Health Organization is shipping vaccines to avoid a repeat of the epidemic that killed 2,267 people, he said.
