Yemen’s Houthis announced that they killed a man suspected of assassinating the brother of their leader, Abdelmalek al-Houthi, last month, saying that he worked for Saudi Arabia.

Yemen's Houthi rebels said on Wednesday they had killed the suspected assassin of the brother of their chief, Abdelmalek al-Houthi. They had previously blamed Saudi Arabia for the assassination.

The Houthis' TV channel Al-Masirah reported last month that the rebel leader's brother Ibrahim Badreddine Amir al-Din al-Houthi had been "assassinated at the hands of traitors" working for the Saudi-led coalition in Yemen.

In a statement on Wednesday, the Iran-backed Houthis said their intelligence wing had killed Mohammad Ali Qaid Dawi, 54, in "a successful intelligence operation" in the city of Marib, deep inside territory held by the internationally-recognized Yemeni government, which is supported by Saudi Arabia.

The Houthis said their investigations had proved Dawi had links to "the Saudi enemy".

The Houthis seized the Yemeni capital Sanaa from Yemen's internationally-recognised government in 2014, prompting a Saudi-led military intervention the following year.

The conflict has since left tens of thousands dead and pushed the country to the brink of famine.
