The Nobel Peace Prize winner Tawakkol Karman has called on the International Investigation Team on Yemen to declare Saudi Crown Prince Mohamed bin Salman, Abu Dhabi Crown Prince Mohammed bin Zayed and the leader of the al-Houthi militia on the list of war criminals.

"The international investigation team will have to announce, on its likely list, the most prominent criminals of the coalition, Mohamed bin Zayed and Mohamed bin Salman, otherwise the coalition will continue its crimes of genocide against the Yemenis," said Tawakkol Karman in her account on Twitter.

Karman added: “It will also have to announce the most prominent criminals of the al-Houthi militias represented by the leader of the fascist group, Abdul Malik al-Houthi.”

Karman considered that unless the report holds the most important criminals of the coalition Mohamed bin Zayed and Mohamed bin Salman and Abdul Malik al-Houthi responsible for war crimes and calls for their pursuit, it will remain a failed report that disappoints the Yemenis and gives up UN duty to provide the minimum international protection for them.

UN-led human rights experts said on Tuesday that the Saudi-led coalition and the Houthi movement had committed practices in Yemen some of which may amount to war crimes.

The experts said air strikes launched by the Saudi-led coalition in Yemen caused heavy civilian casualties in markets, wedding parties and fishing boats that may amount to war crimes.

The independent experts said in their first report to the Human Rights Council that Houthi fighters fired rockets at Saudi Arabia, prevented the distribution of supplies in Taiz, shelled the strategic city from high positions and also practiced torture, which is a war crime.

They added that the Arab coalition forces imposed severe restrictions on Red Sea ports and Sana’a airport, depriving Yemenis of vital supplies, which could also represent international crimes.

They said that further inspections by the coalition forces at the port of Hodeidah also had a "significant impact on commercial shipping," although none of the inspections, by the United Nations or the coalition forces, revealed arms smuggling to Yemen, where 8.4 million people were on the brink famine.
