Saturday, Yemeni authorities executed nine people who were involved in the murder of the head of Houthi's highest political authority carried out by the Saudi-led coalition three years ago, according to Houthi movement.

In April 2018, the president of the Houthi-controlled administration, Saleh al Sammad, was killed in an air strike in Al Hudaydah.

SABA, the official news agency for the Houthis said Saturday that “the Public Prosecution implemented the legal retribution verdict against nine members of the “Alliance of Aggression” involved in the assassination” of Al Sammad.

The death sentence was carried out in public, in the presence of rebel leaders and residents of Sanaa.

Al Sammad, who was killed along with six others, was the most prominent political official of the rebels killed since the beginning of the conflict in mid-2014 between the Iranian-backed Houthis and forces supporting the internationally recognized government.

The judiciary in Houthi-controlled Sanaa tried several people for their “involvement” in the air strike, and issued death sentences for 16 people, including seven in absentia.

It is reported that the death sentence includes Yemeni and other foreign political leaders, including Saudi Crown Prince Mohammed bin Salman, who also holds the Ministry of Defense in the Kingdom, and former US President Donald Trump.

The armed conflict over power in Yemen began with the Houthi takeover of Sanaa and their campaign to control other areas, before escalation in March 2015 with the intervention of Saudi Arabia at the head of the military coalition in support of the government.

Thousands of civilians have been killed in the impoverished country since the start of the coalition's operations, while millions of people are on the brink of starvation as a result of the world's worst humanitarian crisis, according to the United Nations.

Saudi Arabia, which is often attacked by Houthi rebels, announced financial rewards for information leading to the arrest of any of the leaders, most of whom live in Sanaa.
