SANAA, April 17 (Xinhua) -- Yemen's Houthi rebels on Wednesday strongly criticized a veto by U.S. President Donald Trump on a congressional resolution calling for an end to the U.S. support for the Saudi-led coalition's fighting in Yemen.

"Trump's veto proves the U.S. complicity in the massacre against the Yemeni people and unjust siege," Houthi spokesman Mohammed Abdulsalam said on Twitter.

The veto "approves that the United States was not only involved in the aggression on Yemen, but also the decision maker of the war while the others follow its decision," Abdulsalam added.

A day earlier, Trump vetoed the Congress' resolution to end Washington's support for the Saudi-led war on Yemen.

The resolution, approved by the Senate in March in a vote of 54 to 46 and the House of Representatives in early April in a vote of 247 to 175, directs the president to remove U.S. forces from hostilities affecting Yemen within 30 days unless they are fighting al-Qaeda.

Neither the House nor the Senate vote was enough to override the veto.

Meanwhile, the Norwegian Refugee Council said on Wednesday that Trump's veto means "more bombs and weapons will only mean more suffering and death" on the Yemeni people.

"The United States is deepening and prolonging a crisis that has immediate and severe consequences for Yemen, and civilians are paying the price," the international charity said in a statement.

Notably, the United Arab Emirates (UAE), main partner of the Saudi-led coalition, welcomed on Wednesday Trump's veto.

"Trump's assertion of supporting the Arab coalition in Yemen is a positive signal of the U.S. resolve toward its allies," UAE Minister of State for Foreign Affairs Anwar Gargash said on Twitter.

Frustration is growing in Yemen's rebel-held north as the prolonged war and commercial blockade are deepening pains of the residents.

The military coalition led by Saudi Arabia and the UAE intervened in Yemen in March 2015 to support Yemeni President Abd-Rabbu Mansour Hadi after Houthi rebels forced him into exile and seized much of the country's north, including the capital Sanaa.

The United Nations is struggling to save a peace deal between Hadi's government and Houthi rebels, seen as a hope to end the country's four-year civil war, which has pushed more than 20 million Yemenis to the brink of famine.
