The upper chamber of Congress voted 55 to 44 on Tuesday against the measure introduce by anti-war senators.
Their resolution would have forced US President Donald Trump “to remove United States Armed Forces from hostilities in or affecting the Republic of Yemen,” except operations against al-Qaeda or affiliated forces. Those are authorized under a 2001 congressional authorization.

The US has been providing intelligence and logistical support for the Saudi-led military coalition against Yemen.
The vote came as Saudi Crown Prince Mohammed bin Salman is on a trip to the United States.

During Senate debate before the vote, some backers called the three-year-long conflict in Yemen a “humanitarian catastrophe,” which they blamed on the Saudis.

US Defense Secretary James Mattis  traveled to Congress on Tuesday to encourage members of both parties to block the resolution.
  Since it began in 2015, the conflict has killed about 14,000 people, displaced more than 2 million and driven Yemen to the verge of widespread famine.

Much of the Arabian Peninsula country's infrastructure, including hospitals, schools and factories, has been reduced to rubble due to the war.

The United Nations says a record 22.2 million people are in need of food aid, including 8.4 million threatened by severe hunger.
A high-ranking UN official recently warned about the “catastrophic” living conditions in Yemen, stating that there is a growing risk of famine and cholera there.

Earlier this month, Yemen's Prime Minister Abdel-Aziz bin Habtour said Saudi Arabia would not have been able to wage a war on the impoverished country without support from the United States.
