The Saudi regime has failed in its deadly campaign against Yemen to achieve its objectives despite enjoying support provided by Washington and other allies. That is part of a speech by the leader of Yemen’s Houthi Ansarullah movement on the fourth anniversary of the Yemeni nation's resistance against Riyadh's aggression.

Delivering a televised speech broadcast live on Monday evening, Abdul-Malik al-Houthi said Saudi Arabia's “unprecedented oppression” aimed to divide the Yemeni people and control them in order to serve the aggressors' interests.

The campaign is also aimed at occupying Yemen and looting it oil resources, he said.

The Ansarullah leader said it was a religious and national duty to keep confronting Saudi Arabia's agressive behavior.

He also condemned the stance of traitors and those irresponsible people who act in support of Riyadh.

Referring to Yemen's former President Abd Rabbu Mansour Hadi, Houthi said no one has the right to sell his country and to waste the blood of his people.

Saudi Arabia and the United Arab Emirates, he said, are facing economic challenges due to the campaign against Yemen. Houthi did not elaborate on the matter.

Saudi Arabia and a number of its regional allies launched the devastating campaign on March 26, 2015, with the aim of bringing a former government to power and crushing the Houthi Ansarullah movement. Riyadh has failed to fulfill its objectives.

According to a new report by the Armed Conflict Location and Event Data Project (ACLED), a nonprofit conflict-research organization, the Saudi-led war has so far claimed the lives of around 56,000 Yemenis.

The Saudi-led war has also taken a heavy toll on the country’s infrastructure, destroying hospitals, schools, and factories. The UN has already said that a record 22.2 million Yemenis are in dire need of food, including 8.4 million threatened by severe hunger. According to the world body, Yemen is suffering from the most severe famine in more than 100 years.

A number of Western countries, the US and Britain in particular, are also accused of being complicit in the ongoing aggression as they supply the Riyadh regime with advanced weapons and military equipment as well as logistical and intelligence assistance.

Yemenis have been carrying out retaliatory attacks on the Saudi forces deployed in the country as well as targets inside Saudi Arabia.
